Maplestory "High Five" Private Showcase

At certain levels, the Enhancement Cores now unlock additional bonuses:
Level 20: +1 monster hit
Level 40: +20% defense ignore
Level 50: +20% boss damage

And now it looks like each Enhancement Core affects 3 skills at once, and there are overlaps. So maybe you can get these bonuses multiple times on the same skill.

Okay, that makes sense, because the new formulas on the enhancement skills are targetPlus = log20(x), ignoreMobpdpR = log40(x) * 20, bdR = log50(x) * 20.
