Extra Fast

• +100% movement speed for the unique and its minions.
• Only movement: their attack speed stays the same. Older guides said it also doubled attack speed, which the game's code doesn't do.
• Only monsters that walk can have it, so units that stay in place, like Coldworm the Burrower, never get it.
• An Extra Fast Abyss Knightand its minions fire missiles you can't see.

• Ranged characters can't kite an Extra Fast pack: stand at a corner or a doorway instead.
• Slowing effects (Holy Freeze, Decrepify, chill) take back much of the advantage.

Every modifier a unique monster rolls is drawn from the same pool, so each roll has the chance below of being Extra Fast. See how special monsters get their modifiers.

• Only monsters that can walk.
• Its minions move twice as fast too.
