Lowest gear to unlock Darth Malek??

I cleared it (6th try, tough to keep his enrage counter down with that little offense, I struggled to keep it below 12) with g12 Jedi (zzzJKR, zJolee, Bastila)
And g10 zBig Z and G10 zMission.

Only let him absorb the Tenacity Jedi captive and had 6 stacks of armor shred on Malak when I went for it.
