10 Video Game Boss Fights That Broke The Rules

7. Valithria Dreamwalker - World Of Warcraft

Even the most casual observer will be aware that World of Warcraft's more epic boss fights are typically defined by a raid of players organising themselves to take down a colossal behemoth that boasts a titanic amount of health.

But the fight against the Valithria Dreamwalker, a captured green dragon, bucks conventions because it flips the condition for victory.

Instead, you need to heal Valithria up to full health all while fending off the many mobs hell-bent on stopping you.

What's really great about the battle is that it's a rarest of boss fights to grant the focal role to healers, rather than simply having them support DPS and tank builds as per usual.

In a game so thoroughly concerned with bigger, badder bosses, this was a neat change of pace.
