I would agree that summons are overpowered and too useful and need to be toned down... If a summon took 2 hits before it died, that was worth it...
"too useful"... "overpowered"... "2 hits"... good one ^^
Erm, well... I at least hope you were kidding...
Or are you seriously claiming 2 taken hits are on par with already killing the first enemy before he can act or severely damaging a group for the same amount of AP?
@Baardvark
Yes, I concur. As I said, it's the ratio. Compared to what you can do with the AP summoning is right now just not worth it, when most melee skills or offense spell spamm can downright execute most enemies.
... unless they pose a threat ...
Right! And thats exactly why they should have statistics so they can pose a threat! (by improving them or nerfing other things remains undecided)
To justify considerable powers there could be a system similar to the Astralenergybond in TheDarkEye for created entities. Just instead of the Astralenergy (the "Mana" of the TDE ruleset) upkeep it could be action points.
Statuseffect "exhaustion":
"Keeping a creature under control needs concentration. As long as it is active you loose X AP each round."
