I just Spent some time playtesting a few things about crota. To test this your, self never leave the crystal room. Just activate the crystal and receive the presence of crota debuff on the bottom left of your screen and that's when you start your timer. Note: I was testing this in Hard mode not Normal Note: Timers may be a second or 2 off due to me not starting it perfectly once the crystal activates but other than that are very accurate Crota "enrage is near" starts at 9:22 Crota enrages and spawns the oversoul exactly 1 minute after enrage is near so at 10:22 Once Crota enrages you have until 10:37 before your team is wiped. This gives you 15 seconds to take crota shields down and finish him with the sword. Crota Movement timer Starts as soon as you leave the left or right rooms. This is what dictates Crota moving from middle platform to right platform and visa versa from right platform back to middle ect. Crota starts his animation to move to the right platform from the first middle platform right at 1 minute plus maybe 1 or 2 seconds depending on your timer. Once he stops at his destination after moving between platforms you'll have another 1 minute before he moves again. This continues for the rest of his movements. 1 minute for each platform he stops on. Crota immunity timer starts as soon as the animation for crota standing up from being on a knee begins. His orange immunity shield which prevents him being taken down again immidietly lasts 3.5 seconds. A good timer I use is to count to 2 once he starts coming up from his knee then I fire my rockets(gjallarhorn) again. They usually reach him right as his orange immunity shield goes down. Your personal timer will change depending on the velocity of your rockets. Sword timer lasts 45 seconds. I have to stop testing now but I will try to add a timer for how long each sword from the sword bearer lasts also and find out if the sword timer starts when you pick it up or when the sword bearer is downed. Im almost 100% the sword duration timer starts once Sword bearer is downed but I will test just to be sure of this and not spread misinformation like many other posts I've run into throughout my destiny career. Hope this is helpful guys. Just a reminder. I didn't spend days testing these thing probably on 6 hours or so it may not be perfect but it's very close. Feel free to test yourselves to prove or comment on the timers and let me know if I made any mistakes.

3rd sword. 2 time shooting

when he spawns

On hard, it's when crota is 15%
