Treeguard

Treeguards are hostile Monsters that occasionally transform from nearby Evergreens when the player chops down a Tree. They have a lot of health and deal very high damage and are capable of killing an unarmored player in one strike. After day 3, each Tree felled has a 1.3% percent chance of spawning one or more Treeguards. Before day 31, only 1 Treeguard will spawn, then 1 or 2 after day 30, and up to 3 after day 80, given there are enough Trees nearby. They can spawn from any size Tree, including those planted by the player. They take four blasts from the Ice Staff to be frozen.

There are 3 sizes of Treeguards – short (70% scale), normal (100% scale), and tall (125% scale) that spawn from the same size Evergreens. The scale also determines their health, damage, combat range, and walk speed.

Treeguards can be pacified by planting Pine Cones. Planting one at least 16 units away has a 15% chance to pacify it, while at least 5 units away has a 33% chance.

Strategies

 * Kiting with 2-4 hits per dodge.
 * Using the Pan Flute will make him sleep, when he wakes up he will not be hostile towards the player.
 * Lead into Pig village causing the Pig's to aggro against the Treeguard.
 * Lead into Marsh and cause the Swamp Monsters to aggro the Treeguard.
 * Lead to a pack of beefalo during mating season.
 * Burn it using a torch or by leading it to an over fueled campfire.
 * Lead towards other hostile mobs
 * You can lose a Treeguards aggro if you put down a Tooth Trap and have the Tree Guard trigger it. This will cause him to take non-player damage and no longer attack you, unless provoked.
 * Treeguards can be frozen with four blasts of the Ice Staff and then attacked for easy hits.

Trivia

 * Sometimes, after being chased for a while, the treeguard will walk around randomly, not attacking the player. If this happens, use this time to get ready to fight it again, because it will begin attacking the next morning (even if it went passive right after morning).

Bugs

 * More than 1 Treeguard has been reported before day 30 (see image).
 * If a Treeguard is being attacked by a hostile mob, they will turn peaceful after they kill the mob, most likely Hounds.
 * If you attempt to use Straw Roll to sleep while in combat with a nearby Treeguard, the game will not pick it up as being "too dangerous", and you will awake the next day with the Treeguard directly on top of you, still attacking.
