Starforge showdown

I'm sure there are more qualified people as I've not done the event yet, but I see a walkthrough where the goal is to allow Malak to drain the Crit Immunity Jedi and nothing else. It helps stop your team from getting Feared constantly. Also, get as many stacks of Armour Shred on Malak with Zaalbar as possible, so slap your fastest speed mods on him. As for the others, I'm not sure, but there are helpful guides for this event on Youtube.

Edit for context: Using this method, I completed the Light path with an R2 Revan (I think I only had 2 zetas on him at the time), G12 Basti, G11 Mission (Zeta), G11 Jolee (no Zeta) and G12 Zaalbar (no Zeta). I put my highest offense mods on Revan, my highest Speed mods on Zaalbar and stuffed as much offense as I could into Basti, then ran the event and after a few tries completed it, albeit with 1 star.
