The Puppet Master

I've been thinking about this all day at work;

A puppet master/animated puppet combination, with the master being a tank and the puppet acting as an assassin-- think of the puppet Crow from 'Naruto'. I can't decide if he should be from Piltover or Ionia; if he's a Piltie, the puppet could be hextech. If he's from Ionia, then it can be based on magic. The puppet master's goal is to absorbs the life force and energy for other beings in order to bring his puppet completely to life. (The puppet itself full of traps and tricks)

(Passive) - if the puppet is destroyed by an enemy attack, the master gains a shield worth 5% of the enemy's max HP for 8 seconds, when the puppet respawns

Q - charging dash by the puppet in the direction desired, with a cone-like swipe of its hidden blade compartments at the end of the dash

W - the puppets is set to stay in the location this ability is activated, creating a trip sore from its thread as far as the master can travel while staying within the bounds of the ability; can be activated again to recall the puppet, doing damage to enemies in its path on its way back

E - puppet shields the master for a few seconds, triggering a counter mechanism if the puppet is attacked within the ability's duration (the enemy is knocked back while a portion of their HP is absorbed and used as a shield for the master

R - the puppet begins to swell, as it is preparing to explode; can be activated again to detonate, and for every enemy caught in the blast, 10% of their max HP in taken and used as a shield for the master, all while the master gains an additional boost in movement speed and tenacity

What do you think?
