Wow, a very helpful community! That is golden when trying to figure a game out
Well, i guess I will just post the hydra as a lone defender of a border province. And in the next game i wont buy a hydra before im sure i can keep its fellow soldiers alive
Meanwhile i got a new problem... With my astral pretender, I tried my first ritual spell: Astral projection. Well that certainly wasnt worth it... as he was discovered and is now feebleminded

No more magic from that guy.
A pretty big hit to take so early in the game.
How do i remove it?
Seems like a pretty useless spell if the risk is so great? I could easily have sent a scout instead, but i did it to try out a ritual spell.
