The Gunbreaker gets Superbolide, which reduces the tank's HP to 1 but nullifies all damage for 10 seconds. If they heal a total equaling their max HP, they don't die. The Dark Knight gets Living Dead, which, when they die, gives them 10 seconds where all their attacks heal. The Marauder/Warrior gets Holmgang, which doesn't allow the tank to go below 1 HP for 10 seconds. The Gladiator/Paladin gets Hallowed Ground, which simply negates all damage for 10 seconds. Not all invulns are built the same, however. These abilities come with a lengthy recast timer, so tanks must ensure that they only use these skills when a wipe is imminent. Not to fear, invulnerabilities are skills for tanks that stop or delay a tank's untimely demise. Sometimes, the party does everything right, and still, it comes to a wipe. A good rule of thumb that all players should remember is that if there are three or more enemies, do an AoE. Pulling a single pack of enemies is not recommended, as it doesn't make the best usage of AoE attacks. However, wall-to-wall pulls can be intensive for both healers and tanks alike, so if newer tanks are anxious about jumping into the deep end, a good place to start is to pull two packs of enemies, mitigate damage, defeat the enemies and repeat. The tank can recover all of it once they reach the end of the pull. On longer pulls, tanks may find that they begin to lose enmity, but this is okay so long as the tank just keeps moving. The main reason for this is that the more enemies that are hit by an AoE, the more damaging the AoE becomes. Ideally, the best way to do this is to walk forward until the dungeon no longer allows the tank to advance while doing an AoE attack on any enemies they pass (known as a Wall-to-Wall Pull). The tank's job is to grab (or pull) the attention of these packs as the party burns them down. In dungeons, enemies are grouped up into packs.

If all is done right, the tank won't ever lose enmity. To maintain enmity, all tanks need to do is keep doing damage, usually by repeating Area Of Effect attacks ad nauseam. Enmity generation is what keeps the enemy from decimating the rest of the party. If there is a singular tank, this stance must always be on. In full parties of eight players, one tank must have this on (designated the main tank or MT), and the other tank (designated the off tank or OT) must start the duty with this off to not steal enmity from the main tank. In light parties of four players, the tank must always ensure this is on. At level 10, players unlock the tank stance, which increases enmity generation, ensuring that the tank maintains aggro so long as they keep doing damage. For Gladiators/Paladins, it's Iron Will, for Marauders/Warriors, it's Defiance, for Dark Knights, it's Grit, and for Gunbreakers, it's Royal Guard. The first - and yet undoubtedly the most crucial - step to tanking is understanding Tank Stance.
