It seems to me that you need Fresh Vital Essence in every type of beacon fuel, and the only way to craft Fresh Vital Essence is by getting body parts from creatures. The only way to gain body parts from creatures is to fight them, which poses difficulty for those with a pure mining build. I can be one-hit by most creatures in the game due to my allocation of skill points, so it can become a serious grind for me, now, to keep my beacons above water.
Fueling beacons is kind of a really important aspect of this game, and I think it would be good to keep it neutral difficulty for any sort of build, rather than give combat builds more advantage there.
I know this is currently a, “make a new character who specializes in fighting” or, “trade your Ancient Essence for Fresh Essence to a pure fighter” sort of situation, but I feel like keeping beacons fueled shouldn’t be so lopsided.
Edit: I just now realized Minor Beacon Fuel exists. I was looking at the second tier. This only requires foliage. I’m glad for that at least, but this is a bit difficult still because I just tested and you can’t use more than one in a beacon at at time. So your beacons have a maximum life of two weeks. Welp.
