hmm both of those are already done im pretty sure. Hollidays genocide has the attack with radius leach health just changer from leach to dmg. Theres a race called jedi knight that has a saber skill that shoots a ball and if it hits it does dmg so just edit those two skills to your liking and bam you have your skills

yeah like i said it would be similar to both those skills i previously stated you would just have to edit them a bit for what you want. Find a race called Jedi Knight or something of that sort it has a ultimate called light saber. same idea as yours one straight line dealing 60 damage to anything it crosses.
