There's a refactor planned for the medium-long term to skills granting buffs/debuffs and how their stats display which should improve this
When you make that refactor/fix, can you resolve arcane surge/innervate ineractions?
Currently arcane surge/innervate enable supported spells to be supported by duration supports (less duration) but not attacks.
Relatedly, Summon Phantasm on Kill Support + Chance to Bleed Support do not work together, but Storm Barrier Support + Summon Phantasm on Kill Support do*, possibly due to the same interaction as with innervate/arcane surge
*Happened to test this with spell totem - flameblast - summon phantasm on kill - storm barrier, and shield charge - chance to bleed - summon phantasm on kill, both with spiritual aid
