Spider egg sacs in Baldur’s Gate 3 are tiny tools that can sway fights, help with crafting, or be sold for coin. I’m a long-time player, and in my experience you shouldn’t toss them as junk — they have real uses if you know where to look and how to use them.
Where I usually find them in Act 1
I’ve noticed the dens with the heaviest concentrations are the spider caves beneath the Blighted Village well (the Whispering Depths). You can often spot white, webbed clusters on walls and ceilings. The Goblin Camp also hides a few near the temple and storerooms. Why this matters: you’ll save time if you loop those areas while doing quests.
Quick caveat: exact spawn positions and counts can change with patches (depends on your build), so don’t treat locations as gospel. Still, these spots work for most players.
How I extract them safely
Use ranged attacks to trigger spawns at distance. Fire Bolt or arrows are simple and keep your party safe. Stealth works well too — rogues or anyone with Pass Without Trace can pinch a sac without combat. Sometimes I bait a sac with my tank then slam an AoE; it’s messy but fast. This doesn’t always work if you get greedy.
Why these methods? Because disturbed sacs often spawn spiders. If you clear or control that spawn, you avoid wasting action economy in fights.
Quick facts (observed values — may vary by patch)
| Property | Observed value | Note |
|---|---|---|
| Weight | Very light | Carry many without encumbrance |
| Typical sell value | ~5 gold | Some merchants pay more |
| Stack size | Up to 20 | Good for bulk trades |
| Combat use | Throwable | Can spawn small spiders and create acid |
Combat uses — why they matter
Throw them to create distractions. Spawned spiders force enemies to waste turns on weak targets. That’s how you buy time for your big spells. Throwing also often leaves an acid puddle that hurts movement and punishes pathing. Use that to funnel foes into chokepoints.
Want a concrete tactic? Throw one into a Grease field or onto a Webed passage to amplify control. Sounds janky, but it works (watch this: the chaos is real!).
Crafting and trade
Spider eggs go into simple poisons and some alchemical mixes. I keep a stack of 10–15 so I can coat weapons or trade in bulk. Some NPCs prefer ingredients over coin — Auntie Ethel tends to value “exotics,” though I’ll be honest: sometimes selling to her feels like a waste if you need the poison later. Controversial? Maybe. But hoarding paid off for my builds.
Is selling always best? No. If you plan to craft or use poison-coated blades, selling them at 5–8 gold each (observed) can hurt your DPS later. Depends on your niche!
“Egg sacs are small tools, not toys.” — practical advice I use every run.
Practical tips, short and useful
- Bring a Perception-heavy character; sacs hide in shadows.
- Stealth + Invisibility potions = safe picks (useful for rogues).
- Keep 10–15 for crafting; sell extras in bulk.

One odd, useful insight
Sometimes throwing a sac at an ally’s feet (yes really) can bait enemies into AoE traps you set — counterintuitive, but I’ve pulled off clutch saves that way. Between us: it felt lucky the first time.
Two brief controversies to stir the pot: some players treat egg sacs as throwaway loot; I think that’s lazy. Others hoard everything and never trade — that’s also dumb. Balance matters.
Final practical note: experiment. Try different combos, and expect exceptions. You’ll find more creative uses than you think. Happy hunting — may your inventory be useful and your saves frequent! 🕷️✨
