For skills that proc other skills, please provide clarity if the skill tree is used.
For example, Arcane Ascendance can proc Lightning Blast and the tooltip explains that it will use the skill tree and there will be no mana cost. Good job!
But, the Bear companion can proc Ice Thorns. After some testing, it appears that it does not use your skill tree. The tooltip should explain that Ice Thorns will not use the skill tree.
