How to Defeat Nilgal?
Try not to use non-attack skills until Nilgal's Toxic Breath's CD is full because non-Attack skills decreases the CD of Toxic Breath.
Try to stay Debuff free for as long as possible, especially before attacking Nilgal
Make sure Heroes do not have buffs on the turn when Nilgal uses Toxic Breath
Try not to apply too many debuffs on Nilgal, because he might pass it back to us.
Try not to use non-attack skills until Nilgal's CD is full
Due to Nilgal's "Restrict", if we use non-attack skills it will decrease Toxic Breath's Cooldown. We do not want Nilgal to keep casting Toxic Breath too many times as it does quite a bit of damage.

So how do we cleanse if we are not allowed to use non-attack skills?
There are a few ways to deal with this situation:
Save all your heals and only use it when necessary or when the CD for Toxic Breath is full already
Bring Heroes that cleanse and heals on attacks. For example,
Lilias can Cleanse with S3 attack
Blaze Dingo can also cleanse and heal on attacks
Equipping Wondrous Potion cleanses every turn
Try to stay Debuff free for as long as possible, especially before attacking Nilgal
Nilgal and his minions apply a lot of poison debuff on the team. Everytime we attack Nilgal while debuffed, Nilgal will gain Combat Readiness.
Nilgal also has a skill that detonates poison debuffs, which deals quite a bit of damage to the tank.
Make sure Heroes do not have buffs on the turn when Nilgal uses Toxic Breath
Due to "Toxic Breath", the more buffs we have the more poison stacks we get. So don't go too crazy with buffs.
