Raid Shadow Legends – Decrease accuracy debuff can be really strong in Raid Shadow Legends to help your team beat some of the toughest boss fights in the game. When an enemy has a decrease accuracy debuff it will lower their chance to land debuffs on your team, especially if you have built some resistance.
This can also be really helpful in Dungeons, Doom Tower and Faction Wars! There are two versions of decrease accuracy, a 25% weaker version and a 50% stronger version.
