Cupid Build By Achmed ;)

Also the current malice?

The Math has been done (not by me) but yes Malice is statistically better than Rage (meaning Malice has higher dps on average)

honestly after reading the comment above, i learned more about cupid than this build actually taught me. Thanks again Chiulin :) ^^

I don't want to be the first one to have to say this, but... This is more of just a build than a guide. You really need to add a lot more information to this.

You mentioned Flutter is only used for an escape, but from my usage of Cupid it is also an extremely great way to initiate. Simply just Flutter past the enemy. Turn around and then use Heart Bomb followed by Fields Of Love.

Also you shouldn't just tell people to build in any order. From my use of Cupid I would say to just completely remove Frostbound Hammer. Compared to an item like Qin's Sais it is almost useless. Plus you don't need to slow them when you are almost always initiating with the stun followed by the mesmerize from your ultimate.

I also would prefer Malice> Rage. It just seems like I crit more often with Malice. Guess someone will come in here and do all the math to prove a point, but I definitely don't feel like it.

Instead of Bloodforge I think that devourer's gloves work better. Especially for early game. They are cheap and when finished have very high damage and lifesteal. I know that Bloodforge has a higher damage potential. However, after you finally get the Bloodforge passive built all the way(which is what you need to surpass devourer's gloves) you have lost the damage in the first 3 hits that you had lower power. Plus most enemies will cringe by that fifth hit.

Those are just my opinions.
