Righto, so after just completing a nightfall with only a Hunter and Titan (both level 28) we came up with a pretty awesome strategy that I'll try and outline below: [i]Guardians[/i] Titan: Defensive, with weapons of light and damage on the force field to generate orbs of light Hunter: Stealth {don't know what the exact upgrades are} [i]Strategy[/i] So, upon entering the room with the bones in, head up the stairs to the big doors. [b]NOTE: If you go any further back than this room Sepiks will recharge ALL his health![/b]. Pick off the minions as per usual and unload as much of your heavy/secondary as possible (force field with weapon upgrades helps before doing this-damage increases by quite a lot), then fall back into the bone room. Now, one person fired upon Sepiks while the other keeps an eye on the door outside to the left - this is where the vandals and captains spawn from. Once they come out both fall back and kill them off. Rinse and repeat, taking turns and make sure your not too close to each (one should be almost in the bone room covering while the other unleashes his load on Sepiks). This works well until Captains and vandals spawn inside the doors-the person covering needs to be aware of this and as soon as it happens fall back into the bone room and take them out. This happens maybe 2/3 times in the whole battle. Once you've got the routine its a piece of piss (well, it gives you a fighting chance at least!). Good luck!!!
