Vampiric Regen Aura

[Doctor Thantos]

I would like some feed back as well as clarification.

Working on a Vampire Regen power based on Leech and a 2 yard Area of Effect.
I want the power to work with a melee attack (any weapon) and when it strikes the user heals 1 HP.

Based on the following
Leech ( Vampiric Drain aura)
Accelerated Healing, +25% (Does 1 point per 1 point drained / level)
Area Effect, +50% (2 yards)
Costs Fatigue, -5% (Costs 1 point of Fatigue when it activates
Reflexive, +40% (Goes off when attack damages something. takes less than 1 second to leech)
Takes Recharge, -10% (usable 1 every 5 seconds)
Trigger, -10% (Very Common) - in hand weapon causes damage

Its for a Dota like game theme I am working on, so there will be regen for hp and for FP.

Questions,
1.) As written would it drain everything in the AoE when hit? (damage everything in the AoE by 1 HP?
2.) Would the power allow healing of 1/HP per target hit or is it limited to the 1 HP recovered per level of the Power.

Thanks
