really cool trick for hunters for Crota encounter

Hello all Hunters out there. I figured out this really neat trick to regen health during the Crota encounter in Crota's End so I thought I'd share it. Only thing is You do need to be a gunslinger and also have red death with the red death perk unlocked, but what you do is throw a trip mine grenade on the wall or floor or literally anywhere it's NOT going to go off then when you shoot it with your red death and set it off it will actually trigger your health regen. I no u can just shoot a thraul and you will also trigger a health regen but if your between rotations and hiding in the crystal room and dnt want to risk going outside and getting shot at by the boomer Knights or Crota it is always good to have at your disposal.
