As you spend 1 minute to cast this spell, you plant a few beans in the ground as a huge beanstalk erupts from the ground. It grows at a rate of 10 meters per round, to a maximum height of 200 meters. It’s strong enough to support up to 600 kilos total, and has enough handholds and footholds that it can be climbed as if it were knotted rope (Difficulty 5). When the spell ends, the beanstalk withers and dies at an accelerated rate, leaving nothing more than a pile of compost.
You can increase the maximum height by 20 meters and the maximum weight by 300 kilos for each additional mana expended.
