Tree Shape (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 8 hours|
For the duration, you assume the form of a Large living tree or shrub or a Large dead tree trunk with a small number of limbs. All clothing and gear carried or worn changes with you. The closest inspection cannot reveal that the tree in question is actually a magically concealed creature. To all normal tests you are, in fact, a tree or shrub, although a detect magic spell reveals a faint transmutation on the tree. While in tree form, you can observe all that transpires around you just as if you were in your normal form, and your hit points and save bonuses remain unaffected. You have an AC of 20, but gain no benefit from shields or other effects that increase AC. You automatically fail all Dexterity checks and saving throws, and you have a speed of 0 feet.
When you cease concentration on this spell, you instantly return to your normal form.
