What's cool about Manna is how you get large chunk of HP and I also guess you get HPR (but Ivory). However, in this particular build, you have a whopping 11 defense and 11 agi, so you're probably going to die regardless of whether or not you have 1400 more HP and more HPR.

Solution: Build Sitis

https://wynndata.tk/s/2Jfm87 isn't that bad (there are better options of course). I really could care a lot less about -3/4 mana regen when A. that's cancelled out by your natural 5/4 and B. you have 16/4 mana steal. Since Sitis is rather common, it's not hard to get a really nice one.

As a secondary, you can use Black (Matrojan Idol). The mana steal on Black doesn't really matter since you already get so much.
