Count Dooku will cut his own eyes out the minute he sees the Dread Masters. Nox/Wrath/Jadus/Malgus will wtfpwn him.

Can't the individual Dread Masters call upon the power of the others? I recall Sel stating that they share power between them and fighting one is like fighting any of them.

They seem to share a pool of power, but this is largely speculation tbh. Then again it only makes sense, considering fighting them individually takes a team as powerful as it would take to fight them collectively tbh.
