On-hit Tahm

Just try to kill him. Or escape. This is the stuff of nightmares. Double botrk procs + spirit visage + E shield + increased lifesteal at low life from tank masteries, plus devourer is also very extremely awesome with the passive on his ult, which is going to be 20+8% of 1650 before runes and masteries (152), so averaging like 190/hit over 2 hits.
Try it, you'll like it!
Edit: I forgot about the life on frozen mallet when typing this. The total is 2350 bonus not 1650, so that makes for 282 average on-hit with sated devourer finished from his ult (once pbe buffs come through)
much better
