GM has stated before that he's against mining because it's not fun and just encourages bots.
He's basically replaced the concept during events with things like SneakySanta, LootGoblin, GoldenEgg that kind of thing, that you can farm or 'mine' it just requires a bit more interaction as you need to RT around to look for them. So it's basically mining minus the afk bots
i did say put the mining into REL cave ........ and make the boss 140+ so it will be harder to stay in the room and all them people with no clear rings or so on ...... 1hit nightnight lol
REL is one boss what could actually get a revamp and not affect a single thing in the game.
Its not used for quests
It drops such low level items like level 60-78 stuff
Probably is only used to benediction farming
Revamping this to a modern thing means that it doesn't have to be a Savage or Shadow WT/ZT it can just be REL, so no new caves needed just stat and drop improvements.
If you are the same level as this boss you are not making it there, let alone killing it. Maybe change the BastardBats or something but definitely I think this boss is there for the taking in terms of updating it with little to zero impact on fresh players coming up.
I doubt it's even used for bene farming these days, there are much better places for that
i think it used to farm Gems
