Top Poison/HP Burn Damage Dealers – Iron Twin’s Fortress

[Poison] and [HP Burn] debuffs are a prolific way of dealing damage to many aspects of this game, and the release of Iron Twin’s Fortress follows the same trend, with them being one of the most notable ways to take them down, especially with the use of combustion effects.

Today we’re going to take a look at the best options to incorporate into your teams when facing the Iron Twin’s!

What do Poison’s and HP Burn Debuffs do?

The [Poison] Debuff is one of the most powerful in Raid Shadow Legends. Champions who provide these debuffs are an essential part of the Clan Boss fight which takes significant damage hits from this debuff. [Poison] is powerful against Dragon encounters too! A [Poison] debuff hits for a % of the enemy Max Hp either 2.5 or 5%. It is possible to apply lots of [Poison], then use debuff extenders to increase the number of stacks and then use poison exploders to do huge enemy damage!

[HP Burn] is one of the strongest debuffs in Raid Shadow Legends. It is one of the strongest ways to defeat Spider in the highest levels as every time any enemy with [HP Burn] moves it ticks the damage on all enemies. The damage hits for % ENEMY MAX HP therefore the higher the enemy’s health the more damage it does! You can only apply one [HP Burn] debuff to any target and be aware against Clan boss the damage is capped at 50k for rare and 75k damage for Epics and Legendaries per tick! When facing the Iron Twins, this is capped at 50,000 per tick!

[HP Burn] ticks for 3% of the enemies max HP every time any enemy with this debuff moves.

Our Top List:

For us to be able to compile this list, we’re going to have to look at more factors than raw damage output, as this fight is incredibly complex and has lots of things to think about in your team, whether that be the ability to actually survive the fight or providing other valuable buffs and/or debuffs.

There are a few standout Champions who will appear in this list and cover a wide range of roles, but the main focus is on giving you lots of very strong options, and as such, the list is in no particular order.

Geomancer:

Geomancer is the king of damage when it comes to [HP burn]when it comes to his damage reflection, and there’s no change here on the Iron Twins, especially in specific setups where you can abuse the Turn Meter gains from the boss, by running Geomancer alongside multiple buffing Champions, forcing the boss to rotate through turns quickly and die incredibly quickly.

It’s worth noting that Geomancer is probably one of the best Champions in the game for this content, not just in the above-mentioned team setup, but for any team due to the fact he also brings a damage reduction for the whole team, and [Decrease ACC] which is very valuable!

Ninja:

It would be impossible to do a list of damage dealers without mentioning Ninja, with his A2 Ninja is able to melt any boss in the game, by placing [HP Burn] and activating it multiple times.

Ninja also brings 60% [Decrease DEF] on his A1 that fills his Turn Meter when used against bosses, which alongside his Cooldown reduction on his A3 will allow him to cycle through more and more A2s, which will help to kill the boss faster.

It’s likely that because of the damage output from the Twin’s that you will want to go for a rather Tanky build for your Ninja, rather than a damage-orientated one to help him survive the incoming onslaught.

Teodor the Savant:

Well, Teodor’s name has come up nearly every single time we’ve mentioned a top list recently and features in this one again today.

Teodor is capable of so many things, with a wide array of buffs and debuffs to help your team, but also the ability to place plenty of poisons, and trigger ticks of [Poison] and [HP Burn] debuffs with his A3.

He brings 30% [Decrease SPD], 30% [Increase SPD], 5% [Poison] debuffs, 25% [Poison Sensitivity] in his kit all of which are incredibly valuable for this fight.

Neither Teodor’s A2 nor A3 inflicts damage which will help to reduce the chance of pushing the boss below one of its thresholds triggering it to cleanse and attack your team for massive damage.

Dark Kael:

Dark Kael has a very strong kit that revolves around [Poison] debuffs, and also works alongside [HP Burn] champions to further enhance his damage, whilst he is only obtainable from Doom Tower Secret Rooms, he is available from Normal Doom Tower which should make him available to a fairly big portion of the player base eventually – even if you do not have him already.

To start things off, Dark Kael places three 5% [Poison] debuffs and a 25% [Poison Sensitivity] on a single target with his A3 ability, on a 3-turn cooldown, which is incredibly strong but this is even better when you look at how it interacts with his A1 ability, and his passive.

When enemies are under 2 or more [Poison] debuffs, Dark Kael reduces their C. Rate by 15% – Which for those of you who aren’t aware, all PvE Content in Raid is tuned to 15% Critical Rate, so this passive will prevent the Iron Twins from hitting your team with any Critical Hits.

On Dark Kael’s A2 He places a 50% [Decrease ATK] and extends the duration of all debuffs on the target by 1 turn!

So, the final point to look at, Dark Kael’s A1 ability – whilst it does hit 3x and subsequently will do very little damage to the boss itself, it does also have a chance to activate 2x [Poison] debuffs or 1x [Poison] and 1x [HP Burn] which will allow you to ramp up your passive damage massively!

Taya

Taya is another Doom Tower Epic, earned from completing Secret Rooms in Doom Tower Normal, and is absolutely perfect for this fight.

Not only does Taya bring poisons on her A2 with only a 3-turn cooldown to place 3x 5% [Poison] debuffs, but she also instantly activates them and any [HP Burn] debuff on her A3!

Taya also brings a 50% [Decrease ACC] debuff on her A1 which is a hugely valuable debuff to have in this fight due to the high amount of resistance needed without to resist the Iron Twin’s debuffs.

Taya is also Void Affinity so you will never have to worry about weak hits or Strong hits against her!

Kalvalax

Kalvalax is an incredibly desirable legendary for many players, those lucky enough to have him unlock the possibility of incredibly fast speed runs in Dragon and Ice Golem due to his passive paired with poison explosion champions.

Kalvalax’s passive places 4x 5% [Poison] debuffs on all enemies at the start of the round – against the Iron Twin’s this will only take effect at the very beginning, but every turn Kalvalax takes he also has a 50% chance to place one 5% [Poison] debuff.

With his A3 ability, Kalvalax deals MAX HP damage based on the amount of [Poison] debuffs on the target which can not exceed 10% of the Iron Twin’s HP, but a great way to gain additional damage.

Finally, it’s worth noting that Kalvalax extends the duration of [Poison] debuffs on the target with his A1 ability, so you will be able to ramp up a good amount of poisons throughout the encounter.

Anax

Anax is an amazing Champion when it comes to offensive debuffs, as he brings the lot, as well as some additional defensive buffs for himself if he drops low on health.

Anax brings both 60% [Decrease DEF] on his A1 and 25% [Weaken] on his A3 whilst also providing 5% [Poison] debuffs with his a2 that comes paired with a 50% [Decrease ACC] debuff, which as we’ve previously explained is incredibly valuable for the Iron Twins.

Overall, Anax is a great Champion for this content, but you will need to push a large amount of survival stats into the build to ensure that he doesn’t die.

Mithrala

Mithrala is an ideal Champion for this fight, because of how diverse her kit is – and she’s free for everyone with enough work put into the Hydra Clan Boss.

On her A1 Mithrala places 2x 5% [Poison] debuffs, allowing you to push out some damage, whilst also gaining additional survival from the rest of her skills.

Mithrala’s A2 will buff your team with both 50% [Increase DEF] and 50% [Increase ATK], and her A3 brings a 25% [Strengthen] and [Shield] buff, whilst also cleansing your team from all debuffs.

Mithrala is so valuable in this fight because by the standard you will be building her with high accuracy, which also doubles up as resistance for her – allowing her to effectively ignore the debuffs placed by the Iron Twins.

Corpse Collector

Corpse Collector is a nice and simple option for this fight, but also widely ignored in the game because in fights such as Clan Boss she is bringing debuffs that you actually would rather not land on the boss, but it’s not the case here!

Corpse Collector has a [Leech] debuff on her A1 allowing you to stay topped up and healthy while managing the massive AOE hits from the boss.

On Corpse Collector’s A2 she places a 50% [Decrease ACC] debuff for 2 turns, which is massively important for this fight!

And finally, Corpse Collector‘s A3 when fighting a single opponent works as a triple 5% [Poison] debuff ability, on a 4-turn cooldown.

Walking Tomb Dreng

Walking Tomb Dreng was a very recent Fusion, back in July ’22 and has an incredible kit, especially for those who missed out on the opportunity to get Ninja for free!

Dreng instantly activates any [HP Burn] debuffs on a single target with his A1 ability, which goes hand in hand with his A2 which is an irresistible [HP Burn] on a 3-turn cooldown.

Not only does Dreng bring the offensive factor for you with these skills, but he also has a very rare ability that only very few champions in the game have, the ability to equalize the HP of all allies!

To top it all off, Dreng can reflect 30% of incoming damage that he receives back to the attacker, which will only help you kill the boss faster!

Tomb Lord

Tomb Lord has recently climbed the ranks as one of the kings of solo content, since the release of stage 21-25 Dungeons, which actually looking back isn’t so recent anymore with all the content we’ve had drop recently!

A lot of Tomb Lord‘s kit revolves around him landing a critical hit, his A1 – Attacks 1 enemy 3 times, places a 30% [Decrease SPD] debuff on the target if this attack is critical.

Now thankfully, you’ll be building your Tomb Lord with 100% Critical Rate regardless, as his A2 places 4x 5% [Poison] debuffs on all enemies for 2 turns if the hit is critical, whilst only placing 2 if it is not critical.

Alongside his [Decrease SPD] and [Poison] debuffs, Tomb Lord also brings an AOE 50% [Decrease ATK] and 60% [Decrease DEF] which does not require him to hit the enemies, this will always land regardless of affinity unless you get unlucky with the 3% chance to resist (providing you have adequate Accuracy levels!)

Bad-el-Kazar

Bad-el-kazar is infamous as being Raid’s OG Healer, and certainly lives up to the name, whilst there are many Champions who can compete with him on healing now, he still has his place – whether it be soloing end-game dungeon levels, or as a team player, helping to heal your team whilst also contributing to the damage with his poisons.

Bad-el-kazar will help keep your team alive whilst fighting the Iron Twins, but his A2 ability also places 2x 5% [Poison] debuffs for 2 turns, on a 3-turn cooldown – it’s quite common to see people use artifact sets such as Reflex or even Refresh accessories on Bad-el-kazar due to the fact he only has this one skill, so he will frequently drop the cooldown of it even further to pump out more [Poison] debuffs, and more [Continuous Heal] buffs!

On top of this, when enemies are under [Poison] debuffs – your whole team will deal 20% more damage to them!

Urogrim

Urogrim is a slightly budget Bad-el-Kazar, but only slightly, in fact on his release he was considered BETTER for soloing content due to the amount of [Poison]s and healing he put out before his nerf.

Unlike BEK, Urogrim also lands [Poison] debuffs with his A1 ability, whilst it’s only a 45% chance per hit (on a 2-hit ability) it certainly adds up, combined with his A3 that places 2x 5% [Poison] debuffs on all enemies and places a 15% [Continuous Heal] on all allies for 2 turns.

This isn’t Urogrim’s only perk though, his A2 ability heals an individual target by 40% of their MAX HP and removes all debuffs from them – which can come in handy if you’re using a slightly less tanky champion in your team!

Due to the high-speed requirements of the Iron Twins, the 20% Speed Aura may also be massively useful!

Venomage

So, the last Champion we’re going to write about today is Venomage, who also has an incredibly diverse kit that works really well for this encounter.

Venomage brings an A3 that places two 5% [Poison] debuffs for 2 turns, on a 3-turn cooldown – this ability also brings [Heal Reduction] – whilst this doesn’t directly affect the Iron Twins, it does interact with Venomage’s passive ability, which reduces the damage enemies under [Heal Reduction] debuffs heal by 15% – This can be huge for your team’s survival and may just get you the kill!

Venomage‘s A2 ability places a 60% [Decrease DEF] and a 50% [Decrease ATK] debuff the latter being only on enemies that are affected by [Poison] debuffs, which thankfully with Venomage in the team, they will be!

The last bit of Venomage’s kit that works incredibly well on Iron Twin’s is her A1, which hits twice – each hit having a 50% chance of activating up to two [Poison] debuffs on the target to net you some extra damage!
