Mokhaiotl Drift - Master Combat Achievement Example

Mainly posting this so people know you can stall out the beginning of the fight by not getting Doom under 75% health until the volatile earth phase starts, then you can attack and get him near 50% pretty consistently before the shield phase, which means you are very very very likely to kill during car phase to get the achievement Got it first try, good luck (bonus, also got the no grubs 1- 8 achievement)
