I get one level stun, then mana+pod. 3rd level of mana skill is the highest increase, so pod is maxed before it. Always blood chalice.
By the way, I have this insane idea about building HotBL>puzzlebox on her. She could be a Slither-style ganker/supporter/pusher. She already has mana regen and health regen, allowing you to focus on survivability.
I go with 2 skill builds depending on whether laning with mana heavy team mate. I mainly wanted to know what items to start with, mid-game items, late game items and luxury.
I preferably want to build a support heavy.
Start with a courier/wards, a hp pot, and one or two of the Blood Chalice items. Get a :PlatedGreaves: for pushing and survivability. Get lots of :WardOfSight::WardOfRevelation: and eventually aim for :StaffOfTheMaster: or any situational support item if needed more.
