Lingering illusion secondary skill cost bug

DO NOT SOCKET ANY FLAT SPIRIT SUPPORTS INTO LINGERING ILLUSION


When using the lingering illusion buff you can see that it has a cost of 10 mana to summon the illusion each time. However, this is either incorrectly coded or worded and the illusion instead requires that you actually have non-zero spirit available and you have to reserve this additional spirit for the illusion to spawn.

The illusion summoned also gets the same flat spirit cost added to it from supports which doubles the amount of spirit required. Say you socket precision into the lingering illusion gem. The main skill now has a 40 spirit cost and the secondary buff now requires 10 spirit.
