I came up with this idea of a baby scorpion boss and when you kill it it'll drop scorpion parts, scorpion tail, and scorpion poison glands and with the parts you can make acid arrows and a grapple hook
I came up with this cool idea of a spiky woodlouse boss that if you kill it drops woodlouse spikes that you can then craft a armour set that has thorns on it and damages things that attack you, and maybe some sort of shield.
I have came up with this cool idea of maybe adding a dragon fly boss that you can get dragon fly wings from, and then craft a dragon fly glider chest peice that you can glide around the yard in.
