Is there any particular Spartan Ops mission that this can be effectively grinded through?
For all around, I suggest Episode 1, Chapter 4. I’ve been playing this a lot because of the tournament.
There’s loads of Default Crawlers, Crawler Primes, and Default Knights.
2 Crawler Snipers
Around 5 Knight Battlewagons
1 Knight Commander
Around 4 Watchers
Everything for my Forerunner enemies are on Master (with 3 being Complete: Crawler Prime, Default Knight, and Knight Battlewagon) except for Crawler Sniper, but that’s on Expert now thanks to this.
I even got Backstab Complete this week thanks to this.
For just Crawlers and Watchers, I suggest Episode 1, Chapter 3.
