Cast on Minion Death is a persistent buff Meta skill. The skill gains Energy whenever the user's persistent minions are killed. Upon reaching maximum energy, the energy is consumed to trigger the socketed spells.

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.

Item	Description

Version history

Version	Changes
0.2.0	Cast on Minion Death now only gains energy when persistent minions are killed. Additionally, minions that are created by a very underlevelled minion skill (relative to the current area level) now grant less energy when killed. Level 20+ minion skills will incur no penalty in endgame content.
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.
