When you move your cursor over a golem it is not highlighted like other monsters, but every single attack in the game can damage it. This includes melee damage, arrows (using shift) and spells. It would be really nice if we can have the golem be immune to player's attacks or have it behave like other players, being able to get damage by ranged attacks when player ranged attacks damage toggle is on in the .ini.

I've removed the bug label for now as I'm not sure if this is intended or not

Chain lightning crawl table accepting Golem as a valid target sounds like a bug, however I don't think spells damaging the Golem is a bug. However a fix such as ikonomov's could be considered a great QoL feature. I think this issue should rather only be closed with the spells auto targeting Golem is solved.
