The biggest and hardest to kill troll species, these behemoths can regenerate their wounds almost instantly.
Forest Trolls are one of the toughest enemies in Kingdom Rush: they have the most health of all regular enemies, and their regeneration prevents low-level towers from slowly wearing them down. Even Rain of Fire does negligible damage to these behemoths. Thankfully, they are quite rare and have no armour, which should be exploited to the fullest.
- Instant kills such as the Arcane Wizard's Death Ray (which can be combined with teleport) or the Musketeer Garrison's Sniper Shot are generally effective against giant enemies like Forest Trolls, since they are generally much less numerous than other enemies.
- The Tesla x104 is almost compulsory against these enemies - its single-target damage output is unmatched.
- The Sorcerer Mage's Elemental can hold off a Forest Troll for quite a while: the same can be said for Paladins, though backup is required for both.
- Do not waste Rain of Fire on Forest Trolls - they are too strong.
