Patch 6.9: The Return of Tahm Kench

thinks that 6.9 is going to be a splendiferous and engaging experience worthy of a fine gentleman such as himself.

First, take this: http://gameinfo.na.leagueoflegends.com/en/game-info/summoners/masteries/#o.MsUvOgk5.Hn68CXP00

Then, take one of these two gems: or

And finally:

A full build will be something like:

Unkillable. Extremely, extremely unkillable. And terrifying. With infinite sustain.

The math, maxed E, assuming you can avoid popping your shield: Heal 44% of all damage taken base. x 1.25 Visage x 1.1 Keystone x 1.08 Mastery = Heal 65.34% of all damage taken

Then, get 15% of damage taken as mana (you only "keep" about 5% of that 15% damage - remember E!). Get (25% x 1.25 x 1.1 x 1.08) = 37.125% Health from mana spent because healing is fun and mandatory.

So if you get hit for 200 damage, you gain 30 mana, and you really only take 70 damage because the rest heals back. Then you spend 50 mana on a tongue lash and gain back almost 20 health. By the time your E heals you up, you will have literally taken 0 damage overall and had a free Q.

edit: I threw in Warmogs instead of frozen mallet because with Q and Glory, nobody will get away from you anyway. And warmogs gives CDR now. And the heals. The beautiful, beautiful heals.
