Cast on Minion Death

Cast on Minion Death is a meta buff skill that reserves Spirit to trigger socketed spells when reaching maximum energy.

Skill functions and interactions

When one of your minions dies, this gems gains energy based on the minion's power, and once it reaches maximum energy it consumes it to cast all socketed spells in it. It cannot support skills that can create new minions.

A temporary minion expiring does not create energy, but it will if it dies to enemy damage or mechanics such as Minion Instability or Skeletal Arsonist's command skill.

Version history

Version	Changes
0.1.0d	Trigger gem energy gain was not in the right place and it was far too easy to use ailments to trigger spells. One problem with the previous system is that if we balanced it to make triggering happen in boss fights then the triggering would happen far too often during clearing. In order to address this we are now making "Monster Power" part of the calculation for energy gain. This means that it's far easier to trigger skills from Unique Monsters than it is from normal monsters, but you also hit many more normal monsters when fighting. We have also rebalanced all energy gain across the board.
0.1.0	Introduced to the game.
