Myceliaweave Studded Leather Armor

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.

This naturally-sourced armor is interwoven with fibers and caps from a resilient strain of violet fungus that grows when exposed to rejuvenating magic. While wearing this armor, your Constitution score increases by 2, to a maximum of 20, and whenever a spell or magical effect causes you to regain hit points, you also gain a number of temporary hit points equal to half the number of hit points you recover, up to a maximum of 15 temporary hit points. While you have temporary hit points in this way, you also have resistance to necrotic damage.

Curse: Once you don and attune to this magic armor, you can't doff it unless you die or are targeted by the remove curse spell: a side effect of the violet fungus' magical and parasitic effects. When your attunement to the armor ends, your Constitution score is reduced by 2 (to a minimum score of 1) until 2d6 + 6 days have passed or until you attune to the armor again.
