its nice but make a effect to make the life shorter of golems bzw. he loses life overtime or the Golem becomes Damage when the Summoner becomes damage!
I know about the items that use mana, but they're so damn rare, in the most maps there isn't even one item needing mana. You could give him some special abilities to make the spell a bit more original? I got an idea^^You could do something like: A passive ability that absorbs 20(?) mana per attack from the Metal Golem, if he has less than that mana left his mana will get zero and he will take damage instead. That would also fix the one golem at a time thing because they would die anyway after some time;-)
i know, but i when i figured out i accidentally used a autocast spell, i was already too lazy to revert it agian, i will do this tomorrow i think. ehrm, the golem shouldnt have any abilities, and i have given him mana, because some permanent staffs use mana
[EDIT]hehe, i updated now, unfortunately i dont have the necessary modelling skills to make an iron golem´, ;/, but help is greatly apprecieated, ;p, btw do you think i should do it that way that the hero can control only one single golem?
Venom, DON'T RATE BEFORE DOWNLOADING OMG! I'll add a comment to the spell in some minutes when I tested it^^ Edit: I tested it now, it's OK, I'd give it a 3.5, but base it off a none-autocast ability! And another thing, maybe you should remove his mana or give him some abilities.
