Undertale Adventures X Progression
Level fast, evolve mythic units, master prestige Sans, and rank every unit upgrade by value.
What is Progression?
Progression covers everything that makes your account permanently stronger: leveling units to max, evolving mythic units, prestige Sans upgrades, and choosing which unit upgrades deliver the most value per resource.
Why follow progression paths?
Level Without Waste
Fast leveling routes show where EXP pays off and where it dries up.
Evolve Mythics Right
Mythic evolves gate your late-game ceiling, so the order matters as much as the grind.
Upgrade by Value
Value rankings turn upgrade materials into the biggest power jumps first.
