Phantom is by far for me the most fun merc but sometime he feels just broken, a lot of time the blade doesn’t hit anybody when it should have. In this short discussion ill talk about some concept to make phantom even more fun with some new perks he could have.
Life Steal: Re gen 20% of damage done with the blade.
Movement Speed Perk: Increase Movement speed by 10%
Backstabber: Any Back stab makes a Critical
Bleed: any Melee attack makes your enemy bleed doing 10 damage over 3 sec
Undetected: When phantom kills an enemy that hasn’t seen him he Crits
So here was a short list of ideas it may not be really balanced but at least it gives out a concept on how phantom could be.
Sorry for bad english tried my best
