If you strike a group utilizing shared damage and a + defensive buff (for example Kailani) with a -% defensive strike (for example Tiburtus), it will both DISPELL the +% defensive buff and replace it with a -% defensive debuff leaving shared damage active with only the -% defensive debuff.
So, for example:
- Allied card Kailani casts spirit link. Damage is shared amongst your allies and the group gets +63% defense for 5 turns.
- Enemy card Gill-Ra casts Lament of Regression adding -34% defense to your whole group.
- The result of this SHOULD be your team has shared damage, +63% defense, and -34% defense.
- However, what happens is that the defensive buff is replaced and you are left with only shared damage and -34% defense for the whole group.
