Do you guys want to still do this? I think it has a fatal flaw in that we have to roll for everything in battle. I hate ending an RP like this, but I don't see how we can make it work.
I still want to do it, but I think that the best thing to do would be to create multiple solutions to various problems/dillemas.
For example, the need for Soul Thief to be held by someone cursed; while it's a good thing to preserve special roles in the plot for specific PCs, one should also have contingencies for when said PCs' players are absent for some reason. So the solution I would have suggested for that is to create a set of magical gloves that are themselves cursed, but can be used to handle the sword. However, these gloves are
less economical than letting Jotunn's PC handle them, because they grant a temporary - 1 to a given stat.
That way, we can function without Jotunn's PC, but at the same time, it would still be preferable if we had him on our party.
