ToME: the Tales of Maj'Eyal

Only reason I know of is he's trying to avoid friendly fire with the waves

Hey! This is a pretty common issue with golem AI. Sometimes it just refuses to use runes even if everything seems set up correctly. A few things to check:

Make sure the golem has enough energy and isn't on cooldown.

Some runes don’t trigger unless enemies are in a certain range or line of sight.

The AI settings can be a bit wonky—try manually triggering the rune once and see if it works after.

Also, certain mods or updates might affect behavior. If nothing works, it might just be one of those quirks in the current version. Good luck!
