You are correct about the Ritch's Command Attack effect. Correcting...
As for Hydra, the poison breath does damage over time, so it will appear to do less damage.
I'll give the Ritch some armour, defence and melee ability. I'm pondering upping its ranged damage or giving it another talent.
I probably need to nerf the Porcupine a little more.
Will ponder about the Spider too.
The screen blinking is a lua error, but its occurred in the interface code, which messes up the ability to display it. The error will still be in the log file (about 100 times). But I've found the issue anyway.

I'll just tell it to add the stamina pool manually since it didn't work out to do it.
Would you prefer Spit Poison for the Spider Essence or something else?
