Description
A four-sided die used for simple checks. Can slightly level up Traces for Destruction characters.
Lore
The benefit of a four-sided die is that, if you believe in it, it will make every problem easy. Complex dilemmas, unsolvable games, and all those situations you have no idea how to handle — the hard part of it all lies in "not knowing what the optimal solution is." We spend our whole lives with a desire to grasp the power to select, yet spend that same lifetime feeling the anxiety of potential regret. But a four-sided die doesn't need to think about any of that. There is no optimal solution in the life of a die. In other words, in a die's life, all four sides are the optimal solution. "So don't overthink it. No matter what you select, I will declare it: a great success."
Farm it smart
A Trace (skill tree) material. Harsh truth: traces devour materials late-game, especially levels 8–10. Do not level evenly — pour into Skill/Ultimate (your main damage) first, Basic ATK last.
