Combine attempts to combine with a cursed weapon before falling back to a non-cursed weapon. There is no re-cursing. If either of both combined weapons are cursed, the result is cursed with the greater buff of the two. Curse comes in a range, the upper limit is 2.1-times the weapon's damage (component percentages) and generally 2.1-times buffs for cursed items.

It occurs to me that I watch way too many of Dex's Brotato videos.
