Yup, tried a few times with no good results. Watched Ahnald's video then remodded JKR and Big Z, then followed his strategy to victory.
- Stacked offense on JKR (used my GMY mods)
- Stacked speed on Zaalbar (used my JKR mods)
- Use Zaalbar Armor Shred on Malak when available, goal is 4+ stacks
- Kill droids immediately and whenever they reappear, use/call Bastila to ability block droids
- Try to ignore Malak, use Bastila to remove Taunt when able
- Destroy left side stasis fields to prevent Malak from gaining those buffs
- Allow Malak to drain right side Crit Immunity stasis field (tenacity too I guess)
- Use Jolee to heal Big Z
- When all stasis fields are gone and Malak <50% health, beat him mercilessly.
