The quick answer
In Pit of Goblin 1.0.5.0, drinking from a Water Bottle clears Poison and Fungus. You can also throw it and clear those effects from yourself or a friend with the splash. Mushroom traps can be destroyed in the same patch.

Choose who needs the water
Look at who is affected before using the bottle. Drinking is the direct option for your own status. To help a friend, throw the bottle where its water can splash that player. Tell them where you are aiming so they can stop moving long enough to be splashed.
| Situation | What to do | What to check afterward |
|---|---|---|
| You have Poison or Fungus | Drink from the Water Bottle | Check that the effect has cleared before going deeper |
| A teammate has either effect | Tell them you are throwing water and splash them | Have the affected player confirm the effect cleared |
| A throw missed the affected goblin | Recheck the player before moving on | Plan the next action around the effect they still have |
| A mushroom trap blocks the route | Destroy it if the route is worth clearing | Check for a reward and keep a clear way back |
The developer lists both effects for drinking and splashing. If the team has no bottle to hand, make space to regroup or change routes. The patch does not give a drop location or guarantee that every expedition supplies a bottle.
Clear a trap before committing the crew
The 1.0 release added the Undergrowth, an overgrown biome with new traps. When a mushroom trap sits across the team’s route, decide whether you need that route before sending the loot carriers through. Patch 1.0.5.0 made mushroom traps destructible and says destruction can yield a reward. Treat the reward as a possible extra when choosing whether to clear a path.
If somebody has already been affected, call out the player and the status first. Clear the effect with water if you have it, then decide whether to destroy the trap or take another route. Keeping those decisions separate makes it easier to tell what helped.

How Fungus changed in 1.0.5.0
Friendly Foe reduced the severity of spores and the reach and frequency of Fungal Goblin coughing. Fungal Goblin hits now apply fewer spores. The same update addressed a bug involving an infected goblin left outside when the Bucket departed, which could produce repeated noise and spawn more Fungal Goblins.
After treating an affected teammate, have them confirm their status and call the team back together before leaving. If coughing or repeated spawning persists, record the build, the affected player’s status and whether the Bucket had already left. Those details distinguish a missed splash from the departure case the patch describes.
Before the next descent
Use the Journal introduced in 1.0 to review your discoveries between expeditions. On the next run, agree on a short call for Poison or Fungus and who can spare a Water Bottle. If a teammate is missing from the lobby or appears in two different places to different players, use the co-op troubleshooting guide to identify the connection symptom.
