Terracotta soldiers spectre bug

The interaction is weird for me.

I played summoner, had around 300 spirit.

Each of Terracotta soldiers specters cost 10 spirit despite being decently tanky and having decent dmg, so maybe 10 spirit cost is a bug too.

Naturaly, I summoned 33 of them. Most of them didnt spawn "active", but rather the way they stay in crypt, "asleep". So when they spawn, they didnt do anything unless I moved first and they had to follow by respawning

Enemies seem to ignore most of them, probably because while in "sleep" state they are considiered to be objects rather than creatures. Also, when I put infernal army gem (the one that burns minions). it didn't work unless I spawn-respawn them

(Please, just summon a lot of them and run around for a minute, you'll get what's wrong)
