Thanks so much for all of the bug reports. They have been instrumental in getting Thresh closer to release state. This is the final push, so everyone please report any bugs you find over the coming days. Below are a list of bugs that should be fixed with this deploy:

Q Passive visual buff scales more smoothly;
No game lag on lantern initial cast of the game;
Thresh health bar is closer to his body;
Thresh ult goes on cooldown he dies while casting it;
Skarner and Blitzcrank can no longer press the lantern while hooking;
Thresh now has a different temp icon for Q2 (but not the final icon!);
Thresh can no longer cancel the animation for Q by casting it during an autoattack (not sure this one made it in);
Jax/Lee Sin/Katarina can now Shunpo to Thresh's lantern;
Thresh can now gain up to 999999 souls;
Thresh souls now have team coloration;
Thresh souls now move a bit on spawn to be easier to see;
Thresh now has a hidden passive;
Thresh's death animation now plays more smoothly;

We couldn't have identified and solved a lot of these without your help.

any hints on the hidden passive?

I'm a little bit upset about Skarner here. I really wanted to flash in, ult someone, and then get pulled to safety with a present for my team.

How about his armor?

Little quick question, can Syndra interract with an enemy lantern currently?
