Good Way To Grind Xp At Lvl 97?

So im a lvl 97 archer rn and I’ve gotten to the point where the quests don’t give me 99.9% of the xp to the next lvl, so I have to grind for it
Rn I’ve been trying out mirror cave and it works but I was wondering if there was a faster way to get xp other than corrupted dungeons or just any other methods invade I get bored
(And i have tried out slayer quest thingies too so other than those)

 

Sky Islands and Molten Heights secret discoveries, other than that, the methods you already have are good enough

 

Oh yeah, I forgot about those. Thx!

 

Im pretty sure secret discoveries, quests and slaying miniquests should be enough for you to lvl up
