Heartwood Armor (5e Equipment)
From D&D Wiki
Armor (medium or heavy, but not hide), rare (requires attunement by a druid)
Intertwined root mixed with hardened bark, the Heartwood Armor is a piece almost solely from nature. Grafted from great trees by legendary woodsmiths, hardly anything punches through the defences. If you are able to attune to Heartwood Armor, you count as proficient in it's use.
When you end your turn without having moved, you gain 3d6 temporary hitpoints.
