Beanstalk

A 5-foot-thick beanstalk erupts from the ground at a point you can see within range. This beanstalk will grow up to 20 feet within a few seconds. Once it is finished growing, it can be climbed, and the top of the beanstalk, a circle with a diameter of 5 feet, can be stood upon. Once the spell ends, the beanstalk will puff into mist, and any entities still on it will fall to the ground.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the maximum height of the beanstalk increases by 10 feet for each slot level above 1st.
