Fair enough. It wasn't really OP in my campaign though because the GM gave our ranger a greatbow that did 2d20 at level 2 and everyone else got really good stuff as well. The Abyss Walker in our party came in at about level 6 and at that point our bard had a rapier that did 1d10 and ignored all armour AC as well.

Also, I meant the normal deck of many things, not the harrow deck of many things

It has less stuff in it and it runs just off of tarot cards
