[2019] Necromancer Build - Power in Numbers - Last Epoch - 0.7.3

Wandering Spirits have never been minions (they just scale with minion damage), but the Wandering Spirits skill is a minion skill and does work for the node.

The node’s description has been clarified to say “if you have used a minion skill” rather than “if you have summoned a minion”, but I’m not sure whether that description change happened after 0.7.3c or not.
