Chokethorn is a Monster Set (Helm and Shoulder) available in light, medium or heavy armor. It drops in the Chokethorn (unique) style.

The 1-piece set bonus adds 129 Magicka Recovery.

2-piece set bonus: When you use a heal ability, you have a 15% chance to summon a strangler sapling that heals you or an ally for 19565 Health over 4 seconds. This effect can occur every 10 seconds.

The Shoulder can be acquired by using an Undaunted key on Maj al-Ragath's chest. The Shoulder type, weight and trait are RNG based and can be from any dungeon this NPC gives Pledges for.

The Helm can be acquired from Elden Hollow I which is part of the base game and located in Grahtwood. The Helm is guaranteed to drop from the final boss in veteran mode only. The weight and trait are RNG based.

You can mix-and-match Monster Set shoulders and helms from different sets and add two 1-piece bonuses to your build, or wear a complete set to take advantage of the full 2-piece set bonus.
