Makers random Features adds 3 new ores and many more things,lets get into which one they are
Ravager ore,you need to mine a lot to find this ore,its super strong but isnt as powerful as the other armor in terms of protection however has a high knockback resistance,useful for dealing with knockback!
Blazed ore,a rare but not so rare as ancient debris nether ore,it only drops one ingot per ore but is not a normal ore,instead if you wanna get the armor and tools you need to upgrade your old netherite stuff into blazed stuff,however if you get an entire set of blazed armor you get fire resistance,useful for the nether
Withered ore,unlike the other 2 on this list,this one doesnt come from an ore,intead youll need to hunt down wither skeletons,summon the wither and then smelt its nether star to get one gem,sadly all it does is be better armor but it makes you lose your fire resistance,i may update this in the future so you keep the effects per upgrade tier
I also added some enchants that mostly give you effects but are still useful
oh and some mobs but they just exist there
2 new dimensions have been added,the old nether which has none of the new features but sadly has no fortresses and the nether depths,which is curretly still not completly done so there is no recipe on survival to get there,once the dimension is done ill add the recipe
other than that always check te changelog for more things that got added
