last night i killed crota 6 times, on a couple of runs i was able to get his health all the way down to 30% with only one sword. after some thinking i realised that crota can be killed with one sword. REQUIRMENTS full fire team of 31s one bladedancer(will be sword holder) 2 sunslingers (needed to produce orbs of light) 1 Gunslingers (to kill boomer knight and help produce orbs of light) 2 deffender titans (one with weapons of light one with blessing of light) WEAPONS your gunslinger should have a good sniper (ice breaker works well) and his/ her job is only to kill the boomer knights in the left tower and the bridge knight. your warlocks and titans should all have gallahorns preffered and vissions of confluence as their primaries. (VoC decimates crotas first shield as well is amazing for oversouls if needed) STRATEGY many may know this method, I call it "all on left" basicaly as soon as both right room and left rooms are cleared everyone except the bladedances goes to the left side staircase outside the left doorway. the bladedance goes to get the challace and baits the sword beared over to the staircase. while the bladedance is baiting the two titans run down the stairs over to the rock that the bladedancer will stand on to get up to crota, here the titan will both pop their bubbles this will produce at least 4 orbs of light (6 if you got alpha lupi) one of the sunslingers goes to the same spot by the bubble, activate radiance and nade the crap out of the thralls coming from the left tower. the other sunslinger stands on the staircase and uses his/her radiance and kills the thralls in the center around the swordbearer. done correctly you should have enough orbs of light to fully fill the swords super charge twice. first from the staircase, second from beside the rock where the titan bubbles are. once the titans pop their bubbles, the bladedancer has baited sword bear over and the sunslingers have produced enough orbs, the bladedancer, both warlocks and both titans switch focus to the sword bearer untill he dies. Bladedance goes and grabs the sword ****THEN RUNS TO STAIRCASE**** to grab the orbs of light filling the swords super, run through titan bubbles jump to rock and get ready. (make sure you dont take the orbs of light that are generated at the rock!!!! very important) Warlocks and Titans - as soon as the swordbearer dies you instantly switch to dps'ing crotas shield, make sure not to be too fast but you must be fast enough that crota doesnt run away. (if everyone has gallahorns this is easy. 1 gallahorn from each person will take him down instantly. using galla to take down both his first and second shield is the best way for this method. the bladedancer should be at the rock by the time crotas shield at 50% (if your all using gallas for both shields wait till bladedancer is on the rock before you shoot the first rocket) once crotas sheild at 50% - 25% bladedancer jumps up to the left horn on the middle platform and watches crotas shield as soo as the white is just about gone you need to run to him before he is kneeling and hit him with 5 R2 heavy attacks then very quickly use the R1+L1 sword supercharge, jump and R1 twice back to the titan bubbles beside the hiding rock, grab the orbs of light for second sword super ( be very carefull as sometimes you'll R1 back into crota...) the second round of gallahorns are released bladedancer jumps back up to the left horn, as soon as he is about to go down again go in for 5 more R2 heavy attacks and an R1+L1 Supercharge. if perfectly executed you've just killed crota in one sword! Good luck Gaurdians.
