This is the greatest build in the world kills everything so hard that you climb ladders like Gordon Freeman when he looks at them diagonally. Mana is the most OP stat in the game, so do NOT put any points into anything else whatsoever.

Expanded mind is the only mastery that gives you extra mana, so don't worry about any of the other ones.

Just like in the masteries, there is only one thing that gives you mana, which is your ultimate. First though, you should put one point into your Q, so you have something to channel your huge fkin mana pool into. Put your other 17 skill points into your ultimate to raise your mana when you use it.

The Greater Quintessence gives you more mana than any other rune at level 1, so just buy as many as you can. Ignore the mana per level runes because you need that mana NOW. Forget that level 18 BS.

Sapphire Crystal is the one item that gives you only mana, ignore any items like Rod of Ages, because the health and ability power are a waste of gold - you only need the mana. Stick with buying a lot of Sapphire Crystals.

None of them give you maximum mana so ignore them completely.
