What you were expecting to happen, and what actually happened:
Haunted Guardian’s spell says: “Explode Gems in a 3x3 cross”. So I expected destroying 21 gems: a block 5x5 without corner gems.
But it doesn’t work this way. It simply destroys 3x5 block, like a vertical bar 1x3 explodes.
How often does this happen? When did it begin happening?
Just since the troop appeared in the game.
Steps to make it happen again
Take Haunted Guardian in a battle, charge it with mana and cast in a clean area without Domskulls. You’ll see 3x5 block destroyed.
