Beast won’t Reserve Spirit.

I had a beast I could once use but now I can’t use it and my gear or tree have not changed.
I can turn the aura on bind 1 but it won’t reserve spirit. I can turn the aura on bind 2 and it will reserve spirit (12).
Spear/shield in bind 1, I hand mace and no shield in bind 2. If I switch weapon sets to bind 2 beast still won’t summon. I do have a red ❗️ on the beast gem itself but it always had that and would still summon. Reviewing beast itself doesn’t show anything is the red.

So I’m kinda lost in what I’m missing

Are you using any other spirit-reserving skill (i.e. auras, skeletons)? If yes, then double-check the weapons' stats. There's a likelihood that they have a +spirit affix that's covering the overdraw.

Otherwise, double-check your supports. Several have a "increased spirit cost" associated that may be easy to miss.

I have no other minions. I have removed my only other spirit cost gem (herald) even though it was turned off. I also have no support gems attached. Only level 33 btw and the mace on the second bind is not a scepter so it doesn’t have any spirit on it either.
