Just make sure you turn on the non-scoring skull Prophet Birthday Party before starting this level Regret on Halo 2. As long as you finish the level with the skull on, this easy achievement should be yours. The skull can be found on the far right of the second row.

The skull has a 1.00x multiplier which means it's safe to put this on for your first playthrough as it won't void the level completion, or any speed or score run attempts, for any concerned about this. Difficulty should not matter.

Update: Darthmushu confirmed this can be done on easy difficulty with the scarab and other skulls on.
Duality 290 Does it void the achievement if you use Envy and Scarab Gun skull as well?

Messiah Muffin I wouldn't think so. They'd void the achievement for completing the level but I think this one would be fine.

Darthmushu Confirmed you can do it on easy and with scarab or whatever skulls you want on.

Meltoko Thanks Darth. You need to put this advice in your solution.

C3LLDW3LLER So you can put this on on legendary and still complete the level? Does this make the boss easier?
Posted by C3LLDW3LLER on 31 Dec 14 at 16:28
Messiah Muffin The skull is just cosmetic, the boss won't be any easier. Easier is the recommended level of difficulty, but it can be done on any, without completion being voided.

Mattynicklin Don't do what i did and put the grunt birthday party skull on.

Da Slippy Very important to add the skull will only work when in the remastered mode, at least for me, nothing would happen in classic mode, which ended up voiding the achievement so make sure you do the whole mission (at least the prophet fight) in remastered mode.

Dr Drew 9 anyone help with this ive ran through it a bunch of times with the skulls on and no achievement

Kelvin The skull isn't "Grunt Birthday Party" it's "Prophet Birthday Party"

iPlatfoot Oh my god, I wish someone told me about this before dying an infinite amount of times going through this level on Legendary without the skull.

FINALDEATH Did it with scarab skull and even though it counted it made the mission a mission times harder than if i did it without. Wish there was a way to toggle that thing mid mission.

UraMallas Did this with the scarab skull on legendary as well as without any 0x skulls on easy for my speed run. Both times I got the guitar riffs during my beatdown of Regret and both times I was unable to pop the cheevo. Seems to be glitched again as of 30 minutes before midnight on 12/31/2017.

Flint Hisan Did it on Normal difficulty with just the Prophet Birthday Party skull on and it popped as the next level was loading.
