Scratch, Demon of Contract (Support Assasin)

I've been making champions as a hobby for a little while now, and a friend of mine said I should post this one, so here it goes.

Scratch, The Demon of Contract (Working Title)

(Passive) Blood Contract: Scratch binds herself to an allied champion. Other champions may bind themselves to her as well, with a maximum of 3 bound allies. As long as a bound ally is in the general area, Scratch can’t bring an enemy champion below 15/10/5% of their max health, and every time she deals damage, 25% of that damage is turned into stacks of Helping Hand. These stacks burst when a bound ally deals damage to the marked enemy or when the marked enemy leaves combat, dealing 0.5/1/1.5 true damage per stack. If a bound ally kills the enemy, you two split the experience and gold (85/75/65)/(15/25/35)% in their favor depending on their level.

(Ability 1) Penance: The next basic attack lunges at the target, dealing an additional 1/1.1/1.2/1.3/1.4/1.5% (+0.75% AD) of target’s max health as Attack Damage for every kill they have, and 0.5/0.6/0.7/0.8/0.9% for every assist with a minimum of 1.5% and a maximum of 40%. Uses current health if a bound champion is nearby, and increases min. and max. to 3% and 60%

(Ability 2) Vampiric Aspect (Passive): Attacks heal for 4/5/6/7/8% of your max health. As long as bound allies are around, attacks also heal for 30/35/40/45/50% damage dealt and all heal nearby bound allies. 5 second cool down. CDR is only 50% effective on Vampiric Aspect.

(Ability 3) Bloodletting/Blood Frenzy (Passive): Basic attacks apply a stack of Laceration. Laceration stacks deal 3/6/9/12/15% of Scratch’s attack damage over 7.5 seconds. The duration is increased by 0.75 seconds for every other stack, up to 10 stacks. Stacks are removed for every second of increased healing and per instant heal.

(Active): You and surrounding bound allies gain 2/2.75/3.5/4.25/5% attack and movement speed for every stack of bleed applied to surrounding enemy champions and 1/1.5/2/2.5/3% for stacks applied to surrounding minions.

(Ultimate) The Deal: Scratch leaves a ghost where she is for the next 7/8.5/9 seconds and gains +20/40/60% movement speed. As long as the ghost is up, the next time Scratch damages an enemy champion, she teleports them back to her ghost and the enemy champion is suppressed and invulnerable for 4/5/6 seconds. Bound allies in the area are given a chance to teleport to you. If any do 100/125/150 Helping Hand stacks are applied to the enemy champion and the suppress is ended. If none do, you deal 300/400/500 attack damage to them after the suppress.
