Gigacorn at a rate of 0.0013 (0.13% or 1/750)
It does 100 more damage and 1 more tile of radius than Baneserpent and it gives +40 HP and a nice +2 ATK bonus, but it reduces SPD and DEX. It doesn't matter, because assasin already has 75 DEX and 75 SPD so a little bit off is not that bad.
It drops from White Bag and only from Gigacorn.
