I still have yet to understand the bedrock in this game. We wanted to build a moat around our home base in Meadows and even though it was deep enough to work, we never were able to hit water. Supposedly if you kill Trolls before the elder, after you kill the elder then trolls will start to periodically attack your base? So we made that for insurance purposes just in case. I found another Copper Node that I started to work on and as soon as I got about a 1/5th down into the soil, I was swimming around it. Ive just assumed it's a lay of the land type of thing, but I was thinking it was more Mine Craft at first.
Ive been waiting on my g/f to play again before attempting Elder. While exploring around his altar, it's close to the Plains so these little goblin ass (furlings or w/e) fk's will pop up out of nowhere and one shot me with maxxed out bronze armor lol. I kited one with bow/arrow, but they are sneaky af. So I've been building a moat at a distance away from the plains, but between the elder altar so they dont wander over easily anymore. Im just hoping they dont show up while we start trying to kill Groot.
