Guide updated with all new status effects that came with the release of Season III:
Notes on new status effects below:
Brynhild
Brynhild’s dispel protection only protects from having buffs dispelled – so Melendor and Sabina can’t get rid of her buffs on her or allies.
Removers such as Ameonna allies can still remove all buffs though – because a removal superseeds a dispel.
Also, it’s still possible to overwrite her buffs with their opposites. That means Little John can still use his skill and apply a mana delay , which replaces Brynhild’s mana speed buff . Mist can also do the same, as well as replace the Special Skill defense buff with her Special Skill defense debuff
By-Ulf
Note that the ailment shield buff from a flank like Gato can block the boast ailment, and also block the resulting undispellable ailments that follow after Boast’s turn count expires.
Kvasir
Existing minions stay with the owner of the ailment, but no more minions can be summoned until the effect is dispelled or the turn count runs out.
Mist
Note that a special skill defense buff can be overwritten by Mist’s special skill defense down debuff. The reverse is also true, so long as the target doesn’t have the buff block ailment (this can only happen when facing Monks – if the Monk withstands the buff block ailment but not the SS defense down)
Also note that the Buff Block status effect prevents buffs from overwriting negative ailments as well. For e.g. Sir Lancelot can’t overwrite the negative mana delay with his mana speed buff , since the buff block ailment prevents new buffs . However, Rigard and other cleansers can still dispel it.
Sif
The damage reduction buff applies after counter-attack damage has been calculated.
Also note that Rangers can pierce through both the counter-attack buff and the damage reduction buffs
Stonecleave
Unlike Ameonna, he can get hit by Holy enemies. Note that Holy skill effects still don’t work on him – e.g. you can hit him with Chao while in Ghost form, but you can’t decrease his mana.
