Vitiate Force drains Bane.
Vitiate dominates Bane by virtue of being a wound larger than Nihilus.
Vitiate combust's Bane's lightsaber and destroys his sentient orbalisk armor with Force lightning.
Take your pick, this is effortless.
Plagueis would do better, he could command his midi-chlorians to put up mind control and essence drain shields, and other similiar shield that could defend against other esoteric techniques, he could increase his own midi-chlorians, siphon midi-chlorians from all around, slightly weakening the wound's unnaturally superior strength in the Force...he'd constantly revive himself during combat.
Though I doubt Plagueis's mastery of midi-chlorian manipulation was great enough by the end of his novel to contest a nexus as large as Vitiate, but it could have if he'd endured another decade, he may have eventually erected the power and influence to siphon off midi-chlorians from the Chosen One, which would amp his powers considerably, and give him a very menacing technique, more-so than Force/Essence/Life drain.
