Will I get achievement if I use Scarab Skull?

In the collection there’s an achievement for completing Halo 2 on Legendary, but will I still get it if I use the scarab skull?. I wasn’t planning on using it, however, it certainly seems like it would save some time but I don’t want to risk not getting the achievement!

I think you can get colectible achieves (skulls, terminals and such) while using the 0x skulls. Don’t quote me on it tho, cus I think I saw a video with someone using scarab skull to get it faster. But I don’t think you get the achieves for completeing levels, levels on legendary, games on legendary and such if you are using the 0x skulls.

I’ll just do it without then. Just to be safe.
