# Enhancer drop rate
The enhancer bonuses go hand in hand with each other, the higher the value of the Attack enhancer bonus, the more likely it is to have a negative Skill enhancer bonus, and vice versa.
### Drop rate
The bonuses are sorted in two intervals, one for the attack enhancer bonus and the other matching interval for the skill enhancer bonus.
Every two intervals have a percentage drop rate.
More details down below:
* **AE**** =** *Attack enhancer*
* **SE**** =** *Skill enhancer*
* ***%*** **=** *Drop rate*
**1%**** {**-50% **AE** -> 35% **SE**** }**\ **3%** **{**-40% > **AE** >- 49% -> 34% > **SE** > 30% **}**\ **4%** **{**-30% > **AE** >- 39% -> 29% > **SE** > 24% **}** \ **6%** **{**-21% > **AE** >- 29% -> 23% > **SE** > 18% **}**\ **10%** **{**- 1% > **AE** >- 20% -> 17% > **SE** > 10% **}**\ **26%**** {** 1% > **AE** > 20% -> 9% > **SE** > 1% **}**\ **26%** **{** 21% > **AE** > 29% -> - 1% > **SE** > - 9% **}**\ **10%** **{**30% > **AE** > 39% -> -10% > **SE** > -17% **}** \ **6%** **{**40% > **AE** > 49% -> -18% > **SE** > -23% **}**\ **4%** **{**50% > **AE** > 56% -> -24% > **SE** > -29% **}** \ **3%** **{**57% > **AE** > 59% -> -30% > **SE** > -34% **}**\ **1%** **{**60% **AE** -> -35% **SE**** }**
