TREES - Achaea Online Help
Every location in Achaea of Forest, Jungle, or Garden environment type has trees that can be climbed up in, if you have an ability to let you do it in your class skills or the relevant ability in Survival. While in the trees, you can move around with the same exits as the ground has, but if you move into a location with no trees, you will fall out and perhaps break a limb. Oftentimes you will find that those who lurk in the trees above you are spying on you or preparing to do you harm, so be careful and discover ways to see if anyone is in the trees above you. If you find yourself in the trees, DOWN will see you safely to earth once more.
