No need for this bug
What you were expecting to happen, and what actually happened
The imp of love spell is :
“Deal 18 damage randomly split among enemies. Charm a random ennemy. If an ennemy dies, gain 8 Magic.”
BUT, the 8 Magic gain works only if the ennemy die by the 17 damage split. If an ennemy die by the charmed ennemy, the imp doesn’t get the 8 magic.
How often does this happen? When did it begin happening?
Everytimes the damages from the imp kill noone but the charmed ennemy kill someone
Since i started to play this imp 
Steps to make it happen again
Play the imp and try do not kill someone with the split damages and kill someone with the charmed, the magic will stay the same
If this isn’t a bug and the magic gain is meant to work only with the damage split, i think the spell’s description should be :
“Deal 18 damage randomly split among enemies. If an ennemy dies, gain 8 Magic. Charm a random ennemy.”
