My players have started to run amok with the game and I’m loving it, the only problem is I need help creating a move for a new magic item.

My one player is a Charlatan, he’s been using his cherry bombs almost exclusively in battle.  He wanted a way increase its distance and dmg output, so thanks to the help of the party Artificer and a LOT of gold he now has a Predator style  mounted cherry bomb launcher that’s magically tied to his monocle and can retract into a backpack with 3 weight.

.  We were using the volley rules at first but I think it deserves its own move, I just cant figure out what to do for 7-9 for failure it hits the nearest thing, probably an ally, on a 10 it hits no problem.  But I want a hard bargain for the 7-9.   I’m stumped and could really use the communities help.

So I’m thinking When you target lock an enemy Roll+INT on a 10+ you are successful and lock on to the enemy  roll dmg. on a 7-9 Choose 1or 2?.  On a 6- it backfires and aims at the nearest creature/ally( haven’t decided).

   Target lock takes longer to happen and you must put yourself in danger. ( I’d like a more concrete action)

Vampirc Dagger.  When you Attempt to steal someones essence, Roll+Con On a 10+ choose 2 on a 7-9 Choose 1  On a miss it backfires. 

You Steal their essence roll d6 they take that Damage and you heal that much.

You gain their memories and can Spout Lore about things they know.

Vampirc Dagger.  When you Attempt to steal someone’s Soul, Roll+Con on a 10 + gain 3 hold on a 7-9 gain 1 hold on a 6-  The dagger is angry and punishes you, GM tells you what happens.

For 1 hold You Steal their Essence roll d6 they take Dmg and you heal that much.

For 1 hold You gain their memories and can attempt to Spout Lore about things they might know.

I would like advice on at least one more option , and especially what happends on a fail.  I don’t want it to just be dmg.  This is my first attempt at a custom item and help is much appreciated. Thanks for any input.
