Not Updated For Current Season
This is my first time building a toon so bare with me...
Basically start off with Amp Tome (or mana manipulator depending on lane partner and preference) and health pot go back when you have enough for boots of swiftness.
If you can get the mana regen portion of locket pick that up as well...(or amp tome)
basic skill progession is about little damage at the front and support from there on.
Boots of speed are a must I am finding for most games so far...
If your having major issues with nukers or heavy dps adjust gear after locket or tome and gg... the build order is pretty flexible If cool downs are an issue go nashers after locket. If movement is a problem go lich bane after locket ect....
A thought with sona grabbing will of the ancients with heavy nuke group can be win...
(Btw ran a game with a friend using viegar using Sona Hymn of Valor +20 ap and Will of the Ancient +30 ap he was pushing 912 ap and raped every thing... his end score was 34/1/20 mine was 5/4/23)
