As a rogue you're given the abblity to gain grenades by spending gold with the -rogue command. It feels wierd that these items appear out of thin air.
I'd like to see the rogue command given a new feature, spawning a shady merchant for a couple of minutes. He'd have all kind of rogueish things to sell for example poisions, traps, grenades, lockpicks, drugs even(?). Perhaps the merchant can act as a fence for the calling rogue.
