Looking for Do s and Don't s on Tahm Kench

Hey there, Onwodori here.

So GP is getting some secret buffs next patch (Oh lordy, INB4 Tidal Tyrant get emotional at cheaper Zeals, IEs and stronger Steraks!) but for the time being I've really been enjoying the lovely conversationalist Tahm Kench. More than just his kit which used to frustrate me, I enjoy his character --

A slimy, conning, card-shark, smooth talking devil cat fish demon frog. You know. Writing. Guys, he published a cook book, what more do you fu--

Okay I'm back. So how does this whimsically dark fellow work? He was designed as a support but he jungles well and can lane - go tanky and get health with some movement thrown in there, sounds good. But here's where it gets grey like his health:

On hit builds?

?

AP, Magic builds (His scaling with HP and AP are both pretty good, honestly, and W can clear waves mighty well.)

Something like: More mana than he likely needs but hey

That's it. Have fun, you crazy kids. Eat your vegetables~~, don't make deals with frog satan~~
