It's easy to modify the 'fan of knives' so that you can pickup the knives afterwards, and so that it does more damage! In my spell compendium, I will be using the following parameters for shootProjectile,
The last parameter determines whether the projectile hangs around afters, and the 20 is the new damage. This feels about fair. I also made it ignore the party, as it would sometimes hit the party! In my version, I've changed modif so that there are only 5 blades too...Code: Select all

}I did this once for a room I never used... a long time ago... I'm pretty sure you just add the following to the items.lua file.. (make sure you have the spell "push_monster" defined in lua as well). Then you can add the wand_push item in the editor. It basically looks like the lightning rod.LocalFire wrote:I've got a question, how can I add a spell effect to an item?
I want to add Grimwolds pushback spell to an item, so it casts when the item hits an enemy, I've tried onAttack and onUseItem but neither works, is this even possible to do?
