Stuck at 80 spirit, not a bug?

I'm level 90 and found I cannot get 100 spirit, despite having completed the bosses multiple times to be sure.

I have 80 spirit, which should not be possible since the quests give 30, 30, and 40.

Am I missing something? I'm racking my brain but can't seem to figure it out. Sorry if its something obvious ><

I think, 80 spirit shouldn't be a thing. Unless it's like 30+30 from quests and another 20 from item.

FIXED:

It was the vitality gem in Sorcery Ward, which costed 20 spirit.

Sorry everyone, hope someone finds this useful.
