Dragon Era Version 1.8.4

Optifine is strongly recommended. Make sure your graphics/trees graphics are not on fast because BetterFoliage will make trees look glitchy and black.

If you're coming from RLCraft (which I believe will usually be the case) there's still several differences you're going to experience about the game, so here's some tips about them.

The skill upgrade mechanic is from a continuation mod and sadly it doesn't use up experience like in 1.12.2, but actual levels, so if you want to use your xp effectively it'll be a bit harder than just spamming level ups. You can't do it early game, but it'd the decent solution I came up with. XP tomes work a bit differently, making it so you can put in/take out levels by one, so if you're at lvl 20, and want to upgrade your attack to 16, you don't just get to lvl 4 but go down to lvl 16 by storing your XP into the book, and then leveling it up. Then you retrieve your XP and you'll be higher than lvl 4. Sorry if it's a bit confusing, the point is, higher level = more xp, you want to upgrade in a way you end up at lvl 0 after the upgrade.

Stone tools (not weapons though) have been disabled, you'll have to use flint tools, then copper tools, before getting to iron.

Battle towers are sadly not available for 1.16, there's Dungeon Crawl installed instead. They're not as OP as towers were before, so you can't rely on getting all your resources from BTs.
