Steppe, Adventures outpost.

Head north of the outpost near the anomaly for Shroomageddon. Gather a Septic Seed from scolopendras. Finally, return to the Adventurer's Outpost and use the grinder to finish the drink.

Notes

Have you managed to get the Septic Seed from the scolopendra and the Shroomageddon mushroom? We need that poison! Remember to use the grinder!

Dialogue

NPC

Then, there's a particularly dangerous mushroom, the Shroomageddon, I call it. That will pack a deadly punch.

NPC

It's gonna uh.... kill him.

NPC

Wow uh, nice! A free drink?

NPC

Funny how people are so eager to help a killer... Wait, did I just say that out loud?

NPC

By the way, I need you to run something back to Barnaby at the fort.

NPC

So yeah. Get the Septic seed, and the Shroomageddon mushroom then grind it up using the device over there, and give the drink to Gareth.

NPC

Would be nice to have one less witness around...

NPC

Could you procure for me a Septic Seed from one of those many-legged, bitey creatures scolopendras, I think?

NPC

Oh, you're saying 'no'! Classic human response. Lightbearers usually just growl silently.

NPC

Refusal detected! Just let me get murdered.

NPC

Ah, a denial! Fuck me.

NPC

No worries! I'll just have a chat with that wall over there. It seems more receptive than you.

NPC

Oh, hey there! Got something for me?

NPC

Whatever, let's just fuckin' fix this.

NPC

I literally watched Gareth shoot like 10 of our own guys. Nobody bothered asking though!

NPC

Just because I get nervous around new people? We're at war! Everybody is weird until you get to know them!

NPC

I can't believe Zelina thought I was the killer. Like no dude, it's fuckin' Gareth.

Assistant

Now that you have the seed, bro, I'm gonna need you to grind it up and put it in water. Look for the grinder north of our camp, and you're good to go.

NPC

Great. Now get out of here - he's staring at us.

NPC

With those, we'll concoct a, um, special potion, called Mindplague Essence. It's actually pretty mellow. Then deliver it to Gareth with one of your friendly human smiles.
