@loleq80, you either pressed the filter to not show the other monsters, or you have them added in squads! If they are in squads, remove them from the squads first so you can add them to party.
@IronRope you can change the place your summons are at freely!
Its a good ideia to place it in speed right after a dark ritual, and then when you got a good level replace the summons into something more useful!
@tinygamer13, i don't think you can get rid of the potions, but if you get a sludge slime he will help you with that XD
He gives +0.062/s stench.
You also have a chance to get stench when you kill rats and ghouls.
@wereclaw can't you kill some of the monsters in the forest?
just keep doing it until you can summon them! After you can summon them you should be able to complete it without doing it manually.
Put it in the equipment slot. It will activate.
