Item Mastery should not exclude specific items. Increase the duration by a percentage and have it affect all item actives. His kit really doesn't support the use of Zhonya's aside from a defensive item, so it's not like he can abuse the long duration - and Ohmwrecker is so underused it could do with a champion who can "abuse" it. I'm not sure I fully understand the thematic connection of his passive, though.

Can the doll be attacked by allies? Because the only incentive I can see for an enemy to attack it is that it's a ward - but 200-400 (+100% AP) is a lot of health to have to stand around and kill it, and it's a lot of damage to take if you're cursed. It's an awesome mechanic, don't get me wrong - I'm just not convinced any enemy would actually do it. Well, no skilled enemy. This will troll the heck out of low skill players and new players.

The duration of Voodoo Manipulation is too long for a champion-targeted, non-ultimate ability. Also, 1 second stun and 11 second slow isn't even interesting enough that anyone would care it lasts that long.

Black Magic is hilariously OP. and look at Black Magic and have accidents in their underpants. All damage is amplified against the target by 12% and once they've lost ~60% of their health - hit the kill switch. It's not even that the concept if overpowered, but Zed and Vladimir have done it - just the fact is'a (a) true damage and (b) lasts for 14 seconds! It's basically "You cannot join a fight for 14 seconds or I will kill you and there's nothing you can do about it.". It also suffers the same issue as Voodoo Doll... is the doll suppose to be attacked? Why would anyone ever attack it? Does killing the doll end Black Magic's effects early?

It's a very interesting champion concept - with damage redirection and such - but I don't think you've correctly anticipated what enemies will do, and thus I feel the play-tests will have this champion feel incredibly useless (except his ultimate).

Tabu needs to have a way to deal damage to the doll, but at the same time you have to address the possibility of him just placing the doll under his own tower for safety and then just redirecting damage to an enemy without them being able to do anything.

Perhaps make Voodoo Manipulation an ultimate?
 * Tabu begins channelling, forming a tether with the target enemy champion that silences them. After a brief delay, Tabu assumes control for 1.75 / 2 / 2.25 seconds. If the enemy breaks the leash range during the delay, Blood Magic is put on briefly cooldown. Once the connection has been complete, the leash range is significantly increased. Controlling the enemy champion's movement and attacks uses the same bindings as controlling Tabu, who will ignore those commands while channeling. An enemy that is under the effects of Blood Magic is temporarily classified as an ally for targeting purposes. Tabu can reactivate Blood Magic to end the effects early.

I don't really know how to incentivize attacking Voodoo Doll. I guess some Tabu players will use the skill defensively to block skill shots. However, since the dolls aren't automatically tied to an enemy...
