Catalysm

Use Betina's Flasks on living elementals within Lake Mereldar to obtain 8 Active Liquid Plague Agents.

• Active Liquid Plague Agent (8)
• Betina's Flasks (provided)

Coagulated rot is potent on its own, but we need something to activate its concealed powers... a catalyst. You can find just such a catalyst to the south, in Lake Mereldar.

If you look down, you'll notice that I slipped a set of flasks into your bags while you weren't looking. These flasks can be used on the water elementals in the lake. The living, corrupted water that flows through their bodies will be the perfect catalyst!

We're nearly ready to strike,.

Uh oh... it looks like we may have gathered a little too much coagulated rot. Oh well, we'll just have to improvise, then!

What could possibly go wrong?

Use Betina's Flasks on a living Plague Ravager in the lake - you can't collect the Plague Agent from a dead one.
