Maximus

Maximus is a Legendary two-handed sword in Diablo III. It requires character level 60 to drop.

The unique property summons a sword-bearing demon (model based on Oppressor) for 15 seconds. He engages the closest enemy in melee combat, dealing 100% of the master's damage as Physical and being able to draw the enemy attention to himself for quite a long time. The bearer of the sword and the demon are linked with a chain of fire that causes roughly 100-150% Fire damage every 0.25 seconds on touch, to a total of 400-600% damage per second. Both types of damage can critically hit, but do not benefit from elemental damage bonus.

Only one slave can be summoned at a time, but there appears to be no cooldown. The sword also offers a considerable Fire skill damage bonus.
