How to reach Spider Cave and farm Prismatic Heart
Prep strong armor and weapons, as the spider hits from range with minions—dodge attacks and use crit-focused builds.
Step 1
Unlock Island 3 (Frostspire Expanse) by completing Sensei Moro’s quests for the portal tool and hitting level 70.
Step 2
Travel to Spider Cave entrance in Frostspire Expanse; it's the same cave from initial Raven questline.
Step 3
Push deep into the cave, clearing smaller spiders until you spot the Prismarine Spider boss at the edge or spawn point.
Step 4
Defeat the boss—auto-attack, AFK farm if safe, or dodge ranged attacks; repeat as it's not a 100% drop.
Step 5
Loot the shimmering multi-colored Prismatic Heart when it drops; expect ~1/50 tries.
Prismatic Heart rewards and uses
| Use | Reward / Benefit |

| Overall Questline | Unlocks Dragon Head Pickaxe (2,750,000 gold) after obtaining all 3 hearts |
How to complete the full cult questline
After getting the Prismatic Heart:
Step 1
Enter Raven Cave via Red Cave key from Raven bird quests.
Step 2
Reach secret chamber past glowing orb; interact with rightmost Auron NPC (E key) and submit heart.
Step 3
Farm Yeti Heart (Peak Cave) for Mjelatkhan, then Golem Heart (Ice Golem boss, Summit’s Edge) for Morveth.
Step 4
Once all are submitted, get the Dragon Head Pickaxe for 2,750,000 gold.
Stock extras for forging instead of selling - their multipliers dominate late-game builds. Once you've powered through the cult quests, that Dragon Head Pickaxe elevates your mining empire in The Forge.
