Material Breakdown & Best Farming Spots
Poisonous Slime
Essential for every Venom rune, Poisonous Slime is dropped by a range of low‑level slime creatures. Prices are mostly stable, but Citra shows a climb to 20 GP (max 20 GP) while Epoca holds steady at 40 GP.
- Drop sources: Brimstone Bug, Diremaw, Filth Toad, Ink Blob, Lancer Beetle, Sulphur Scuttler, Toad.
Best farming spot: The Poisonous Swamp in the southern part of the Darklands (near the Seaweed Altar). The area spawns all listed creatures at a high rate, and the swamp’s thin water reduces travel time.
Slime Heart
Without a Slime Heart you cannot complete a Venom imbuement. Most worlds show stable to modestly rising prices; Citra peaks at 120 GP (max) while Epoca’s price is fixed at 0 GP (no offers). This suggests a strong sell‑side on worlds with active markets.
- Drop sources: Blood Beast, Brain Squid, Cave Devourer, Rage Squid, Squid Warden.
Best farming spot: The Underground Sewers beneath Venore, especially the “Squid Lair” section. These monsters have a high kill‑per‑minute ratio and respawn quickly, making it ideal for bulk Slime Hearts.
Swamp Grass
Only dropped by Swamp Trolls, Swamp Grass is used for the secondary slot of Venom. Prices diverge heavily: Astera’s sell offers skyrocket above 1500 GP, while Blumera reports zero sell offers. If you need Grass, buy on worlds with a stable market (e.g., Descubra at 484 GP avg.) and transport to your target world.
- Drop source: Swamp Troll.
Best farming spot: The Swamp of Sorcerers south of Port Hope. Swamp Trolls respawn every 10 seconds and can be farmed safely with a low‑level torch.
Creature Hunting Activity & Event Influence
The ongoing Full Moon period has slightly increased spawn rates for the slime‑type monsters, especially in the Darklands and the Venore sewers. However, the Demons’ Lullaby event does not directly boost poison‑related drops, which explains the muted demand on worlds like Epoca and Belobra.
Players focusing on Venom should:
- Prioritize hunting in the Darklands (Poisonous Slime) and Venore Sewers (Slime Heart) during full‑moon nights for a ~15% boost in kill speed.
- Watch the market on Citra – a rising trend suggests a short‑term profit window before the Full Moon peaks.
- Avoid heavy investment on worlds with volatile or falling trends (Blumera, Astera, Dracobra) unless you can secure a good bulk discount.
Investment Recommendation
Overall, the Venom market is moderately attractive. The safest play is to:
- Buy low on Citra for Poisonous Slime (currently 16‑20 GP) and consider flipping after the Full Moon price surge.
- Hold existing stock on Epoca and Descubra where prices are stable; sell when a buyer offers a premium.
- Delay purchases on Blumera, Aethera, and Astera until price volatility subsides.
- Farm locally in the recommended spots to offset market costs, especially if you have spare backpack space.
By balancing market speculation with on‑the‑ground farming, you can maximize profit while ensuring you have the necessary materials for those deadly Venom imbuements.
