I’m guessing not many folks use them, but I was actually tempted to buy 13 or so off hand weapons and have one of each type.
But I’d rather just carry one extra weapon, to avoid the constant weapon swapping. So how about letting us combine different sigils of slaying together in the mystic forge to create a super sigil that does damage to all creature types that have been forged together?
Maybe charge 25g for the item required to hold the sigils to offset the cost of the weapons ppl would otherwise have to purchase.
