Tresh the Chain Warden!
Tresh is in the midst of live balance passes and therefore any of the information below are subjected to change.
Tresh is a supportive champion that can be also be played in Jungle or Top lane. The main characteristic of Tresh is that if he uses his tools properly he can lock down a single champion for a long time. He has quite clear disadvantages of low mobility, reliance on skill shots and on the ability of his allies to capitalize the momentums he can create.
Keeper of Souls (Innate): Thresh does not gain armor or magic resistance per level. Instead, he collects the souls of enemies that die near him. Souls permanently grant armor, magic resistance and ability power.
The souls can be dropped by minions while they are guaranteed to drop from Champions. Tresh has to pick the souls by walking near them. The first soul will grant 1 bonus ability power, armor and magic resist. Subsequent souls will grant 0.01 less, down to a minimum of 0.5 per stack. This will stack indefinitely.
