Grythion, the Celestial Griffin appears in Rotation 2 and 3 in the Doom Tower. This challenging encounter will force you to build a team specifically designed to counter her mechanics. Let’s break it down.

Shockwave
Attacks 1 enemy. Has a 100% chance of placing a [Fear] debuff for 1 turn.

Rock Smash – 3 Turn Cooldown
Transfers all debuffs from Grythion to each enemy, then attacks all enemies. Fills Grythion’s Turn Meter by 5% for each debuff transferred.

Death Gust – 3 Turn Cooldown
Removes all buffs from all enemies, then attacks all enemies. The buff removal cannot be resisted. Damage increases by 10% for each buff removed.

Divine Strike [Passive] Attacks an enemy whenever their HP drops below 50%. This attack places a 100% [Heal Reduction] debuff for 2 turns.

Celestial Bond [Passive] Adds one [Sky Bond] buff to Grythion at the start of each turn. Also adds one [Sky Bond] buff to Grythion whenever an enemy’s HP drops below 50%.

Each [Sky Bond] buff increases Grythion’s ATK by 5%; C. RATE by 3%; C.DMG by 5%; SPD by 2.5.

Will ignore [Shield], [Block Damage], and [Unkillable] buffs when Grythion has 10 or more [Sky Bond] buffs.

Can stack up to 20 Sky Bond buffs. Sky Bond buffs cannot be blocked or removed.

Fair Wind [Passive] Whenever [Grythion]’s Turn Meter is decreased, the Turn Meters of all enemies will be decreased by the same amount.

Places a [Stun] debuff for 1 turn on enemies with fully depleted Turn Meters. Whenever an enemy’s Turn Meter is filled, Grythion’s Turn Meter will be filled by the same amount. Turn Meter increases are tracked and counted individually for each enemy.

Almighty Immunity [Passive] Immune to [Stun], [Freeze], [Sleep], [Provoke], [Block Active Skills], [Fear] and [True Fear] debuffs. Also immune to HP exchange effects.

Almighty Tolerance [Passive] Decreases the damage taken from poison debuffs by 90%.

Almighty Strength [Passive] Damage from skills that scale based on enemy MAX HP cannot exceed 10% of the Boss’ MAX HP when attacking the Boss.

Almighty Persistence [Passive] All Turn Meter reduction effects are decreased by 50% when used against the boss.

Grythion is the ultimate Enrage boss in Doom Tower. His Sky Bond Passives will cause his damage output to become far too much to manage once he reaches stacks above 10. Therefore, you need to manage how he gains these stacks. He will gain a stack each turn he takes and also when any member of your team drops below 50% HP.  Your team should be tanky enough to ensure you never drop below this threshold otherwise it significantly speeds up his enrage timer. Additionally, anytime you do get hit below 50%, you will also get hit again and with a Heal Reduction debuff making it harder to lift that champions HP back up to full.

Maintaining Decrease Attack on the boss at all times will be extremely valuable in mitigating the risk of dropping below 50% HP. We highly recommend you bring an A1 Decrease Attack champion to increase uptime of the debuff. The boss will transfer debuffs back to your team when he activates his Rock Smash ability meaning long cooldowns for Decrease Attack are not recommended.

Bringing shields and other bonus HP effects to help mitigate incoming damage is also a good approach to take. You’ll want to be careful with the Buffs and Debuffs you bring to this encounter. More buffs = more damage when Grythion activates his Death Gust ability and you dont want to be receiving back substantial debuffs unless you can plan to cleanse these. Alternatively, consider bringing a Block Debuffs ability and time this to be placed before he transfer the debuffs back to you.

To take down Grythion, we recommend you consider a combination of HP Burn and Warmaster or Giant Slayer Masteries as you will struggle to fit any champion who isn’t built reasonably tanky.

Main things to Avoid:

1. Turn Meter Reduction: If you deplete his turn meter, your whole team will lose the same amount of turn meter that you deplete – if this results in a fully depleted turn meter, that champion will get stunned which can be hugely problematic.
2. Turn Meter Boosting: Grythion will gain equal amounts of turn meters which works out to be very counterproductive as it will force him to take turns faster, thus gaining more Skybond stacks.
3. Many Buffs and Debuffs: These will be removed and either transferred to you or empowering the boss’ damage.
4. Low Defense/HP Champions: You want to always stay above 50% HP so the boss doesn’t gain extra stacks. Having champions who are easily able to drop below that threshold will just cause your run to fail sooner.

The key stats you should consider are Accuracy and Speed on your team alongside good HP/Def to survive the damage. Depending on the strategy you’re going for – you may need to push high offensive stats too.
