Sandworm down at level 9. What a pain. Bartz could deal 175-190 damage with the Moonring Blade, but it was hard to deal damage at all when I was being spammed with Wave Cannon Quicksand. Boiled down to RNG and it not using Quicksand, my winning attempt had it do a lot of normal attacks.
Going to need to steal a lot of Silver Bows to sell for rods. Beating world 1 at level 9 may be doable, rods should take care of Soul Cannon and Purobolos. Archeoaevis will have a 1HKO in Frost, but if necessary I can grind bows for flame rings. Manticore will also have a 1HKO but that's just a matter the Berserker deathing it before it kills me. Titan is probably the biggest question mark, since I don't think I currently have a way to avoid Earthquake. Unless Mute works, but I doubt it. Ah right, Titan is vulnerable to Stop. So yeah, that covers everything I think.
Levels so far:
I got to level 4 in the wind shrine before Wing Raptor.
Level 5 before Siren.
Levels 6, 7, and 8 came in the Karnak escape, from the Ribbon, Elven Mantle, and Main Gauche chests respectively.
Level 9 came from the Harvester encounter I got the Death Sickle from.
