At what depth are core fragments in Starbound

Weapons are all up to preference.

I've found that swing speed doesn't matter much as timing your attacks is more helpful than just spamming attacks.As for the spear vs. warhammer, the warhammer would be easier to hit with since it does an overhead swing, whereas the spear does a forward thrust.

Another thing to look at when comparing weapons is armor penetration, as that seems to be more important than straight damage.

Monsters can be captured by crafting a Creature Capture Station at tier 4, then using that to craft Capture Pods. These pods can be thrown at small, grounded creatures with less than 50% health to have a small change to capture them.
