"Every weapon Tier produces a specific amount of power level boost to its user. For the White Tier, it boosts its user's power by 5 percent, and these is subdivided into one percent per Grade." Little Lin began to explain.
"From then on, the amount of increase per grade rises as we ascend. At the Peak of White Tier, the user's total strength is 5 percent. Then as we enter into the next tier, the increase is doubled per grade." She continued.
"So, for the White Tier, the increase is one percent per grade. But for the Grey Tier it increases by two percent per grade. So, if a Peak-grade White Tier weapon increases power by five percent, then a Low-grade Grey Tier would increase the power output by 7 percent."
"Likewise, for a Peak-grade Grey Tier, power level is increased by 15 percent. Afterwards, the increase is doubled once again at the Black Tier, and as a result, a Low-grade Black Tier weapon would increase power output by 19 percent."
