This assumes you're entering Caelid after Liurnia around level 60, weapon upgrades +10 to +15 normal and +4 to +8 somber. Caelid is tough due to Scarlet Rot, aggressive enemies, and high damage output; use Preserving Boluses and bring Rot-curing items.

• Western Caelid, near the border with Limgrave.
• Straightforward mine with good loot (Moonveil katana is excellent for INT/DEX builds).
• Boss: Magma Wyrm
  • manageable with dodging its fire attacks and using the arena space. Great starter dungeon for upgrades and a strong weapon.

• (Northwest Caelid, under the Minor Erdtree)
• Trap-heavy catacombs with imps and two Erdtree Burial Watchdogs.
• The double boss can be cheesed somewhat (e.g., with Crystal Darts to make them fight each other).

• Eastern Caelid
• Prison-themed cave with vulgar militia and exploding corpses.
• Requires 2 Stonesword Keys.
• Boss: Frenzied Duelist.
• Linear and ambush-heavy but short.
• Rewards include Regalia of Eochaid (arcane weapon) and Wakizashi.

• North of Swamp of Aeonia
• Crystal mine (you can get teleported here early via a chest in Limgrave).
• Good smithing stones and Somber Bell Bearing.
• Boss: Fallingstar Beast

• West of Impassable Greatbridge
• Skeleton-heavy with Scarlet Rot pools and aggressive Miranda flowers.
• Boss: Cemetery Shade.

• Dragonbarrow / northern Caelid
• Rot-filled with two Cleanrot Knights as bosses.
• Very hazardous due to Scarlet Rot buildup.

• Beastmen bosses in tight spaces.

• Putrid Tree Spirit boss.

• More puzzle/trap focused, with Battlemage bosses.
