So what else do we have to do?
Strictly speaking nothing, we can pick some appropriate stats from a monster manual/bestiary (or create some) and run with the monster as it is, however, there are a few additional questions that we help us flesh out the monster a bit more.
What does the monster look like?
We’ve already described Kalkedos as being green of skin and ugly of aspect, however we can flesh this out a bit further, keeping in mind the reason for his curse; since he was a greedy, grasping man I envision him as having long arms and powerful muscled hands that can shoot out of the water, grabbing prey, throttling it and dragging it below the water. Kalkedos also has large reflective eyes used for scanning the swamp for treasure and any trespassers attempting to steal what is his.
What abilities does it have?
Physical power is Kalkedos’ main ability, however the god who punished him did not want him to die in the swamp (since that would end his punishment) so Kalkedos regenerates all but the most vicious of injuries in time, however, no matter what he stuffs into his huge fanged maw the creature is always lean and permanently hungry, denied the ability to sate his urges and lusts.
What are it’s weaknesses?
Since Kalkedos is always hungry he is easily lured with food, his greed also leads to him being attracted to shiny objects whether or not they have any actual worth; however he is unable to look upon the truly beautiful since it reminds him of what he lost, seeing people or objects of great beauty drives him into a rage and he will go to any lengths to smash the offending object/person.
Is there a way to break the curse?
Besides the god of merchants, the only way for the curse to be broken is if the dead merchant’s daughter or a direct descendant of hers, forgives Kalkedos his crimes and can convince him to leave the swamp; if this happens then his warty troll skin will slough off and he will be restored.
