DeathKnight solo anything bug. As far as I know it only works on Eternion WoW.
Its actually quiet simple, a no-brainer, but its still a useful find. If it helps you I would appreciate the rep.
Basically you death grip to pull the mob, and do not move, and the mob will be in your exact spot, allowing you to hit it, but it cant hit you. Then rotate until your facing the npc's right side.
1. Deathgrip a mob without moving
2. Rotate until your facing the npc's right side and attack it
You CAN death grip it mid combat, but it has a lower sucess rate. This bug allows you to become an excellent tank while in DPS gear.
This only works on melee mobs. SPELLCASTERS CAN STILL HIT YOU.
If this is a repost let me know, I didn't see anything like it.
