Explore mode has 12 difficulty settings, each defining its own upper and lower level limits. Each setting is more difficult than the one before. Difficulty increases as you progress towards the final battle and ideally peaks with the m-m-mythic boss battle. This keeps the experience within a predictable range of valleys and peaks and allows for players to develop a sense of progression.
To illustrate, this is what explore mode opponent level valleys and peaks and difficulty settings look like:
You’d expect world events to follow a similar pattern.
They don’t; battle levels increase independently as every preset battle is a separate ‘explore’ run in itself. This leads to some rather… funky? results because there’s no lower bound for difficulty.
Just beat a level 500 battle? Surely your next opponent’s going to be level 425-525?
It’s level 20-40 battles for the next seven sigils for you.
Let me accurately illustrate world event difficulty progression:
I’d enjoy the game more if world event level progression worked a tiny bit more like explore mode’s.
