Mortal Shell II Weed: Trollweed Effects Explained
[QUICK ANSWER]
Find the early Trollweed pickup near the opening spawn point, then learn what the item description says about its immediate effect and 1,000-item threshold.
Quick answer
Mortal Shell II weed refers to Trollweed. At the start of a run, turn around after gaining control and check behind the spawn point, beside the nearby house and campfire. The item description jokes that Trollweed does nothing at first, then records a total-damage-immunity effect at 1,000 Trollweed in the inventory.
Where to find the first Trollweed
- Take control of the Harbinger at the beginning of a new run.
- Turn around instead of following the first forward path.
- Check the side of the house behind the spawn point, near the opening campfire.
- Pick up the Trollweed on the ground.
This is an early collectible, not a merchant purchase or a combat reward. Grab it before leaving the opening area if you want to track the item from the start.
What Trollweed does
The item description presents Trollweed as a rare plant with no immediate effect. The same description gives a 1,000-item inventory threshold for total immunity from damage sources. Treat that threshold as the item’s documented joke effect: do not assume it is a normal heal, crafting ingredient, or combat buff at lower counts.
The available item wording does not establish a button prompt, duration, toggle, or separate activation menu. Do not replace Mother’s Pulse, Weltcap, or another known combat resource with Trollweed based on the threshold text alone.
Collection advice
Pick up Trollweed whenever it is on your route, but do not build a farming route around an assumed respawn rule. The opening pickup is the reliable location anchor; a complete inventory-count route is not needed to understand the item’s purpose.
