No entity ranking is possible — here is what the data supports instead
The official description names steps, speed, multipliers, Heaven, Hell, Galaxy, races, and auras — but no catalog of comparable entities ever appears. The shop's multiplier passes are the closest thing to a roster, and even they document prices, not in-game effect sizes. Importing a roster from a similarly named game, or inventing aura tiers, would make this page look complete while giving players fabricated advice.
What can be compared honestly: the documented pass prices (below), the world route order, and the training loop's free-vs-paid split. That is the data a spending decision actually rests on.
