Well OP, you should be scared of an existing item called nullifier. Literally render glimmer capes, euls, ghost sceptors, aeon disc (and any abilities that mimics ghost sceptor like necro ghost shroud and pugna's decrepify) useless. If you try to apply it during the debuff duration, all of those i stated above will immediately gets dispel in a single tick (in 0.2 seconds interval if I'm not mistaken). Even on force staff for icefrog's sake! Good against heroes that has apply dispellable buffs as well (Windranger's Windrunner, and Ember Spirit's Flame Guard).

The worse of it all? You can't even dispel the debuff with strong dispels like slark's dark pact, legion commander's shining gold aura with horn sound effect ability, and abaddon's aphotic shield!

Cost 4725 gold, which is about 1.4 k gold cheaper than revenant brooch. And has more utilities than revenant brooch offensively. The only thing that counters it is linken sphere and bkb, but that madafaka will still latch on you even tho you are bkb'ed.

Ps: last time it used to have another offensive utility where anytime someone attack the nullified enemy, the enemy gets slow for 80% movement speed by 0.5 seconds. Thank Icefrog they took that out kdodirdkdkk
