Eraser Hand V3

Deal damage by rolling a d5 + half of the user's wisdom and half of the user's intelligence, rounded up, and the damage dealt is the result of all three, added up. You may also choose to roll a d20. If the result is 15 or higher, You may destroy a target creature/opponent. (It instantly dies, and it is dealt damage equal to it's hit points and cannot be resurrected.)

If you are level 7 or higher, this spell instead deals damage by rolling a d10, + the user's wisdom and the user's intelligence, added together, and the result of the addition of all three of those properties is the damage dealt.
