First guide. wanted to share,.

using Q options:
1. you want to use it to slow the enemy for jungle gank
2. you want to apply stacks
3. you want to stun enemy

early game, I generally apply stack 1 or 2 with Q, or any stack 2 or 3 by Q, auto attack, or even spitting a minion at them. Trading is very effective ~ level 3 or 4 because of the shield from E.

late game, you can harass with Q. and in team fights you try to auto attack and then use Q for stun.

W options:
1. eat minion and split at enemy to apply stacks
2. save teammate
3. eat enemy to make it 5v4 etc.
4. eat teammate to chase

very situational. I find myself doing all 4 options throughout the game.

options E:
use shield = save ur life. its just like tryndamere's ultimate except you have a shield instead. Normally when trying to save a teammate or dive, I use the shield when my health is very low and then bust out FOM on top of it. Tahm is very hard to kill if you can get your E off.

options R:
in solo q, your teammates are ******ed. It's hard to pull off a successful team gank with the ult.
2. you can also cut off enemies by using your ult if your team is chasing them a certain direction.

you can also cancel your ult by trying to walk resulting in a 10 sec cd only.
