Archvillain

Archvillains are extremely powerful entities. They con +5 to their level. They typically have tens of thousands of HP (ten times that of standard bosses), substantial regeneration, increased damage, and near-immunity to mez two-thirds of the time. Approach with extreme caution and several teammates.

Archvillains will spawn as weaker Elite Bosses against teams which are small and/or using low notoriety settings.

Archvillains are also noteworthy for having strong debuff resistance that scales by level. As of Issue 9, this resistance applies to -RunSpeed, -Recharge, -Endurance, -ToHit, -Defense, -Perception, -Regeneration, and -Recovery.

So, for example, while it might seem as though a Defender's Radiation Infection should be valuable against Captain Mako in the Statesman Task Force, to deal with his Elude, it is in fact heavily resisted. 3-slotted, it would do -61% Defense, which should cripple him, but as it's against a +4 enemy it is at half strength (-61 * .5 = -30.5), and as it's against a level 54 Archvillain a further 87% of that is resisted (-30.5 * (1 - .87) = -3.965%), leaving the net effect approximately a third as useful at bypassing defense as an Insight inspiration. Likewise, even against an even-con AV, a 50's Lingering Radiation's mighty -500% Regen debuff will be dropped to approximately -65%.
