Pocket Bomb Spell Request

Level 4
Nov 23, 2014
Hi guys me again so.. I saw an awesome spell that it will turn you invisible for a few seconds and if you collide with an enemy unit it creates a unit or timed bomb but it was far too difficult for me to understand so I can't import it, I was wondering if someone could make that spell for me and has three levels of it (I'm still new to triggering so pls bear with me) Thanks in advance :3
