I killed five lynels

Majora's Mask in its game: *insanely overpowered magical artifact capable of destroying the entire world with the Moon*

*skips*

I managed to kill my first white Lynel with a few flurry rushes, so I think I am ready

There are five lynels that appear in this order: Red lynel, blue lynel, white lynel, silver lynel, and silver lynel again but with rock armor. You need to kill them in order to gain access to the chest that contains Majora’s mask. I forget the location of the colosseum except that it’s somewhere in the Depths.

Directly below the colosseum on the surface, central Hyrule northeast of the Great Plateau, iirc.
Also, if you leave, you can come back later and it saves how many Lynels you've killed (unless there's a blood moon). I know this, because I broke my master sword on Every Single Lynel and had to leave for 10 minutes so it could regen
Also, the last silver lynel broke all but one of my shields, and it was Badly Damaged

This mask is a LOT harder in this game.

Thanks, also noted
