Hello!
I am having trouble with Drifters in caves: there are so many of them, and they respawn as quickly as I cut them down.
Often, I can't get past a cave's first wide open / dark area: Drifters set on me, and while I can hold them off (losing HPs and durability on my spear), I can't beat them back and delve further.
I have leather armour and a black bronze spear.
When possible, I retreat to stairs that I've cut into the cave wall and place a block behind me to create a two-block-tall barricade to defend. The Drifters will pull back after I hit them a few times, and so I remove the block and give chase to finish them off. However, as soon as I clear the group that attacked me, more Drifters turn up and another fight starts. Low on HPs and with my spear about to shatter, I break off and flee the cave.
I bring fence segments to set up a perimeter around an ore deposit so that I can keep the Drifters off me while I mine. But I can rarely stay in a cave long enough to find anything!
Am I doing this wrong?
