What you were expecting to happen, and what actually happened:
Guild War battle. My last surviving troop (Ilithian Colosus) could not do any Skull damage against Axolotl, which was submerged.
How often does this happen? When did it begin happening?
In this combat, I did no skull damage despite 5 or 6 matches. It is the first time I’ve noticed this.
The Submerge trait avoids damage against the whole team, but skulls damage only the first troop. Is this a bug? Or a badly worded trait?
