I have a question about this bouncing spell. Instead of making the spell bounce between monsters, how can I make it so that the spell casts multiple blasts from the player, with a 200-unit interval between each blast? The spell should be based on a maximum of 6 targets, meaning if there are 6 targets around, it will cast 6 blasts to those targets
LUA:

bounceSpell.targets = {targetId}
bounceSpell.currentTargetId = targetId
bounceSpell.lastTargetPos = player:getPosition()
