What you were expecting to happen, and what actually happened:
King Avelorn deals damage to all Enemies and summons a Forest of Thorns troop however it is also increasing the stats for all troops including its self. See pics
How often does this happen? When did it begin happening?
Noticed it today in PVP Winter’s Reach with Elf restriction.
Steps to make it happen again
Battle in Winter’s Reach where King Avelorn is in the enemy team.
I’ve notice the same. But I think it’s not only King Avelorn but any toop in enemy team that can summon. I think it’s something with Blook Frenzy +50% to skill points, as the increase in skill points seems to be the initial 50% of toop’s skill points.
