Desert

Desert sits in the level 60-90 window of Sea 1, the stretch right after you graduate from the early starter islands and start needing real damage to keep up. The arid biome is built around the Desert Bandit and Desert Officer, two grind-friendly NPCs that respawn quickly and let you push levels in tight loops, plus the Desert King, the island's boss. He's the headline reason to stop here: clearing him is the rite of passage for this bracket. Two pickups make the visit worthwhile. The Desert Skirt is a cheap, easy armor piece that's a sensible first cosmetic-stat upgrade at this point in the game, while the Sand Fruit is a genuine draw — a Logia-style fruit worth grabbing if it spawns nearby. Practically, farm the Bandits and Officers in a circuit rather than chasing single kills, and once you outscale the Desert King and approach level 90, move on toward the next Sea 1 islands. Don't over-stay; Desert is a stepping stone, not a long-term grind spot.
