Trees

Trees

Trees are neutral units that spawn throughout waves. They can be killed for good Loot.

Trees drop 3 Materials on death, and have a 100% to drop a Consumable. This consumable has a base 20% chance to be a Loot Crate, which increases with Luck.

Note that unlike the Loot Hoarder, trees are not guaranteed to drop consumables. So if you have negative Luck, or are playing Endless Mode, trees might not drop consumables.

Thing	Effects	Notes
Tree	Increases the amount of trees that spawn.	Grants on average 0.33 trees spawned every 10 seconds.
Lumberjack Shirt	Allows you to kill trees in one hit, as if the tree had 1 HP.
Explorer	Starts with the equivalent of 12 Tree items.	Also, the first group of trees spawn at the beginning of the wave instead of 10 seconds in. (But the second tree spawn is still after 20 seconds just like with everyone else)
Cryptid	Starts with the equivalent of 6 Tree items.	Does not have the early trees feature that Explorer has.

Spawn

Trees have a chance to spawn every 10 seconds. The first chance for trees to spawn is 10 seconds into the wave. The exception is Explorer, whose first spawn of trees happen at the start of the wave, but the second spawn still happens after 20 seconds for Explorer.

A random number between 1 and 2 + your Tree Secondary stat is chosen.

Then the game will attempt to spawn a tree with a 33% chance that number of times.

This means that every 10 seconds, an average of 0.5 Trees + 0.33 times your Tree secondary stat spawns.

So for Explorer, who starts with a Tree stat of 12, a average of 4.5 trees will spawn each 10 seconds.

Neutral

Trees are Neutral. This means that they aren't affected by some effects like Gentle Alien's ability to increase the amount of enemies. They also don't count against the maximum number of enemies that can be on the map at once.

In the same manner, Jack doesn't increase the amount of Materials dropped by Trees. (But their HP increase)

Bouncing Attacks like the ones from Slingshot do not target neutral units when finding a target for their bounce, but the bounces can still hit trees if it crosses the path of the projectile.

Furthermore, Burn doesn't spread to Neutral Units if you have the Snake item. You can still set the tree on fire by attacking it directly.
