What you were expecting to happen, and what actually happened:
If there is only one enemy left then this enemy is the first and the last, so twice the damage is expected. I think I remember another troop having this behaviour, but the skeleton key seems to only do the damage once if only one enemy is left. Could be that game mechanics changed and the other troop where I’ve seen it before now also works differently and this is now a feature not a big.
How often does this happen? When did it begin happening?
Happens very rarely.
Steps to make it happen again
Noticed it at pet rescue because troops at last levels have quite a lot of life and armour and then the skeleton key did not kill the last enemy…
