Conjure Clamberwood

You cause a tree to sprout from an unoccupied space of solid soil that you can see within range. When you cast the spell, you determine the height of the tree, which can be a maximum of 20 feet. If there isn’t enough room for the tree to grow to full height, the tree attains the maximum possible height in the space available. The tree trunk fills a 5ft square and has evenly spaced branches perfect for climbing. The tree has AC 5 and 25 hit points. After 24 hours, or if the tree is reduced to 0 hit points, it instantly withers away.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can increase the height of the tree by 20 feet for each slot level above 1st.
