Dynamo Util Heal Team Pull

Skill Unlock: 1-3-2-4

Good enough to sustain your teammates, be useful in teamfights

Improved Reach, Superior Cooldown and Superior Duration on 4

You will most likely have to remove another active item if you want to add both unstoppable and refresher
I also really like the combo Shadow Weave + Phantom Strike because it makes much easier to hit a good ult
