Star Wars Jedi Survivor - Rancor Easy Kill (Grand Master Difficulty) - Koboh Cheese Tactic
If you want to kill the Rancor on Koboh in Sodden Grotto in Rambler's Reach early on, you can easily do so with lightsaber throwing.
All you need for it are following skills:
"The Power of Friendship" from the Survival tree

Once you're down in the pit you wanna get hit by the shockwaves only, they won't kill you but will allow you to use a stim to regenerate Force. Evade all his other attacks.
