This may be a stupid question, but our Overlord insists that this is possible:

Can the overlord first play dark charm on a hero and then afterwards enrage this hero to give him two attacks against him- or herself?

In my opinion this isn't possible since it states on the Enrage card, that it is only possible to play enrage on a monster, and dark charm doesn't magically transmute the hero to a monster, or does it?

we just had this discussion before in the forum. you might want to try search. in short, no he can't.

I thought so, thanks. I had tried using the search function with 'charm enrage', but I didn't find the post you are refering to.

In addition to not being a monster, the charmed hero is not being activated , just making a single attack. So it fails to meet the triggering conditions on two counts.
