When using Hades in Invasion boss fights the following steps will result in a bug.
- Hades is reduced to 1 hp and activates his red skill.
- Hades Red skill invincibility wears off and Hades is reduced to 0 heath, activating his purple skill.
Hades revives to full health. - The invasion boss is defeated with Hades taking no damage after reviving to full.
- Hades does not appear in the list of champions which can be revived by the revive booster.
- New boss battle begins.
- Hades is reduced to 1 hp and activates his red skill.
- Hades Red skill invincibility wears off and Hades is reduced to 0 heath, killing Hades.
So in my opinion, one of two things should happen here: either Hades needs to be revivable in the revive heroes screen which will reset his purple skill or it should automatically reset each time between battles. If Hades takes any damage before the boss is defeated then he can be revived and his skill reset. I have only observed this from Hades but this may also apply to any other hero with a revive ability that can restore themselves back to full HP.
