As you begin to progress in Boundless you will find that the more complex materials require components that cannot be farmed or mined. Bones, creature organs, tallow, blood, leather, and creature trophies originate from, you guessed it, creatures! Higher tier planets will yield more resources from the creatures found there, however, the creatures will also be tougher and possibly elementally infused. (See Elements) These drops because of their demand and the method of gathering them can be exceptionally lucrative, certain trophies can be worth thousands in coin. (See the section on “Knowledge Tab” to learn how to check the buy/sell prices) As you explore planets, kill the creatures you encounter. A gold fist is a good choice as a hunting tool early on, and remains viable into the tier 4 planets. Beyond that more advanced elemental weapons or forged fists are recommended to overcome the elemental creature variants and more difficult creatures.
All wildstock are generally passive and require provocation before they will attack, they attack by rearing back and rushing the player with a headbutt. Regen bombs will count as provocation, as well as firing a weapon or striking at any other nearby creatures regardless of whether they are hostile or not. Note that when spawned by a meteor these creatures are aggressive and will seek out players to attack.
Most spitters, except those on the Tier 1 planet, will be hostile. Spitters launch projectiles from their snouts. These projectiles can sometimes be singularly fired, rapid fired directly at their target, or sprayed in a fan pattern. Spitters can also launch bombs which will damage all players within range when the bomb impacts.
Small and round, hoppers are amblitory bouncing bombs. They will arm themselves when the player comes within range, although this takes them a few seconds during which they are vulnerable to attack. Once armed the hopper will make a high pitched whistling sound, then try to detonate itself beside the player. If the hopper is defeated after having armed they will still detonate. It is therefore advisable to eliminate them either before they arm, or with ranged weapons once they have armed. Hoppers will drop volatile blood instead of the other blood types. Hopper Cores and Hopper Eyes are among the more valued crafting materials.
Cuttletrunks are flying tentacled creatures that will attempt to bombard the player with projectiles and beam lasers from above. They can employ multiple cluster bombs which will then each split into even more bombs all of which will detonate simultaneously. Elite variations also have an ability to levitate the player up and drop them to the ground inflicting fall damage on the player. Ranged weapons work well for eliminating cuttletrunks.
Fast and noisy the roadrunner is always non-aggressive and does not spawn from meteor portals. If a roadrunner detects a player nearby it will begin to squawk at the player then will make a mad dash away from the player at high speed. They will sprint until the player is no longer within threat range then return to their passive stance. It can be useful to grapple a roadrunner to keep it within range of either a fist or slingbow. Roadrunners will damage themselves when trying to climb cliffs and will suffer fall damage if they fall from a great height onto a hard surface, they can also be chased into lava. A persistent player can often run them to death even if they are unable to target the roadrunner. Roadrunner drops include adrenal glands, roadrunner feather, and lean meat which are exclusively obtained from the roadrunner. Additionally roadrunners can drop raw oortstone, which is only otherwise obtainable from meteors.
