ToME: the Tales of Maj'Eyal

First time playing ToME, and i chose a mage. Good stuff, having fun in the first dungeons.
But sometimes, my golem decides not to play, just standing in a corner, not attacking. Here, P was my character, and E was the enemy.
My gnome just stood there, watching me die?
It can just walk around right?

AFAIK Golems will only attack enemies that they can see, not necessarily targets that their master is attacking (if they can't see it as was in your case above), CMIIW.

At times like that, it's best to 'pull' either your Golem or the enemy around that corner, so your Golem would be able to see (and attack) your enemy.

Just my 2 cents.

PS I don't play Alchemist much, but from the couple of times I play it, that's how I observer the behavior of my Golem.
PPS don't remember whether there's a command where you can simply order your Golem to attack an enemy, regardless of whether your Golem can see the enemy or not.

Ah, that makes sense, thanks for clearing it up
