Tree Growers can be placed on Spring, Summer and Fall Islands only, and will tend to the trees that are scattered across the island. The growth time will depend on 2 different factors; the friendship of the monster and the overall tree level of the island.
This tree level is a hidden level that goes up as you use the Spirit Wand to grow more trees. You will be able to tell that the level goes up by a skill increase sound playing, as well as a sudden growth of the huge tree that holds the doorway and the storage. At max level, trees will only take a week to grow to maturity.
When trees do mature, a Rune Crystal has a chance to drop. These will only appear when they mature, and you will not get another one until the tree is mature again. It is about a 25% chance for one to drop, so you will see them regular enough to collect a nice stockpile of them before you need them. These Rune Crystals are also amazing healing items, but are best saved for creating items that need them.
There are only 2 types of trees available, Oak and Maple, both in a wide variety of shapes and sizes... some even look like palm trees! Since there are only 2 kinds, there are only 3 classes of these monsters; Oak Growers, Maple Growers, and ones that do both.
All King monsters will be highlighted in RED.
