User blog comment:Deshiba/Item concept; Guinsoo's Rageblade remake./@comment-5333760-20130521060122/@comment-4022742-20130523090415

"..2 major stats from 2 core items" <- Technically not true, it's kind of like the same concept from You loose the Health regeneration, but gain Spell vamp in return.

Same for my version of the rageblade. You get flat penetration, and when the game progresses so far that the flat penetration form these items isn't enough, you upgrade it to give percentage penetration.

I did make a mistake with the cool down reduction though, two 10% items should give more then just 10%.
