2. A character with a strong enough cloak buff (e.g., a mage with 5.3 million HP)

Method

1. Go to Darnassus or Silvermoon with a character whose cloak is super strong by doing the Landing Expedition

2. Find your class trainer and enter the Training Grounds

ㄴProbably only class trainers in Darnassus and Silvermoon are possible. Maybe only Night Elf (+Worgen?) & Blood Elf classes will work

3. Slice them up.

ㄴHere, the dangerous stages where you might get sliced up are

Here and

I can't find it on Namuwiki... there was a stage where two Large Vision Conquerors appeared. Might be a bug.

It is recommended to use a cooldown even if only one Large Vision Conqueror appears

One Large Vision Wind Guardian is manageable with a semi-cooldown (like Ice Block for mages), but 3 in wave 6 is painful

*The stage mentioned above is the defense stage

The attack stage doesn't involve getting hit, and I don't remember it since it was a long time ago

I don't know about the healer stage because I can't do it with a mage. I'll have to raise a priest.

Possible to reach defense stage infinite wave 30 with a mage

Healing stage is impossible... the tank dies (can't even pass bronze)

Maybe possible if you're a DPS that can steal the tank's aggro or heal party members

Since stealing the tank's aggro alone won't heal party members hit by AoE, a DPS with party healing seems right
