Some are easy, some are difficult.
You probably could solo most of them as BRD (with a lot of kiting for some), but it'd be safest to go with a friend or go as SCH.

You can hold up to 2 maps: 1 deciphered, 1 in your inventory. And then each retainer can hold one.


The spawns you can get are as follows:
- Gelid Eye - Ahriman. Uses Void Fire II, Stone, Stone, Stone, then Level X Petrify which has a very short casting bar. I recommend spinning him around after that 3rd Stone until Petrify goes off.
- Bombast - Just a bomb that swells up in size once in a while then explodes. You can kite when he's swelled up. Kinda funny to watch.
- Slipjaw Ogre (x2) - Just two ogres.
- Drakes (x4) - Four drakes that use frontal cone breaths.
- Dire Gargoyles (x4) - Four gargoyles that use line AoEs.
- Ziz (x3) - Woad Back, Gold Back, Wine Back. I recommend killing them in that order. They're on a timer to use their breath attacks, and Woad's petrifying breath will go off first, then Gold's paralyzing breath, and finally Wine's poison breath.
- Golem - Summons two waves of four bombs as your wear him down. If you don't kill the bombs within the few seconds they're idle from spawning, they'll home in on you and explode on contact.
- Monocular Biclops - Summons two waves of tiny peapuks. The peapuks don't take much to kill, but there are a -lot- of them so they can hurt.
- Morbol Menace - After a while, the morbol binds the target (can be removed with Esuna/Leeches), and then uses its breath (can be stunned to prevent it from going off). Not sure if a BRD can solo this one; I know I couldn't kill it before that bind as a BRD with i100 weapon duoing with a tank.
