i have 0 spirit

So i tried to unlock talents that requires spirit but i couldn't, the game said i have 0. then i looked for some info and found out that usually each player has 100 spirit in the beggining and you get some spirit after defeating bosses. So i defeated the count (main boss in the act 1) but still have 0 spirit. How do i fix it?

players can obtain up to 100 spirit by the end of the campaign, everyone start with 0 spirit. there's nothing to fix, play the campaign.

Act 1 (normal) Freythorn - King in the Mist gives 30 spirit.

Act 3 (normal) Azak Bog - Ignaduk gives 30 spirit.

Act 3 (cruel) Azak Bog - Ignaduk gives 40 spirit.

You can get spirit from gears too like chest, amulets and helmet and there is also a soulcore (socketable) that grants spirit.
Good luck.

And also a Sceptre gives 100 spirit (while equipping in main hand or off-hand).
