It depends on boss for the ogre and witch hide behind rock kill eyes snipe ogre once ogre dead rush to top use exotic void sword power swing if I'm missing a lot with it I use super warlock stormcaller. With the one were the floor is poisoned kill acolyte stand in light shoot witches shield once shield is down jump to top shoot or use sword on witch when I'm about dead pop super to get full health use use super on witch jump down rinse repeat. If it's mini crota kill sword bearer down crota kill crota he is the toughest solo just because his shield regenerates so quickly
