I'm converting existing characters from another game system into a slightly modified version of RMU. We had an existing campaign we want to convert to the new system, but I have a problem with one PC, because his main weapon was a chain.
In RMU that's not an ordinary weapon and I should rule it as an improvised weapon, but i find this a little too punishing since in the other system it was a proper weapon with stats and all, so a legitimate choice for a character's primary melee weapon.
I thought I maybe could consider it a peculiar form of Whip, with Krush instead of Slash criticals, but I'm not sure. How would you rule it?
