Forests of Training are high difficulty, 0 stamina, 20-stages long battles permanently available at the Extra Isle. Upon completion, the player receives a special item, usually a new ship (and a rainbow gem). A new Forest of Training is added to the game every few months.
In those quests you won't obtain any reward from the enemies except the one-time clear reward for each stage (ship+gem). You cannot use a gem to revive upon defeat, it's do-or-die.

Difficulty[]
While in-game, all Forests are ranked equally in terms of difficulty, in practice older forests are easier. Hawk, Beard and Flame Fist are considered easiest. Several forests can also be completed with reasonably forgiving zombie-teams if you have the right subs and/or ships.
