Use a fantasy fight to study the transition between committing and recovering.
The three actions need a relationship
Giant Killer mentions upgrading heroes and developing dodge, defense and attack. Naming those actions does not explain how they fit together in an encounter. Before trying to optimize a hero, watch for a visible point where an offensive action ends and another decision becomes possible. This gives you a concrete part of the exchange to investigate without inventing a combat system from the fantasy premise.
Make one encounter readable
Choose an action the game itself explains and observe what follows it. Does your character remain busy, can you move, or does a new prompt appear? These are questions rather than confirmed mechanics. If the next enemy action is difficult to address, ask whether you committed before understanding it or simply missed a control. Adding more attacks may obscure that distinction.
Upgrade after naming the limitation
If an upgrade menu appears, connect an offered effect to the limitation you observed. A defensive difficulty does not automatically justify a more expensive attack option. Equally, a failed attempt does not prove that the hero lacks statistics when the sequence itself remains unclear. The supplied description is truncated and its controls are generic. This note cannot identify an invulnerability window, a character build or a tested counter; it offers a way to make the next comparison more informative.
