Use your ultimate as much as you can. Getting more statues means getting stacks on the ultimate passive, granting permanent str + int.
Can opt for Conduit Gem instead of Sands. Focus only on farming unless forced to fight early.
more cooldown = more damage, more opportunity to spam your ult during teamfights. Very useful on Medusa since her damage is hybrid scaling.
Helps with proc'ing Totem of Death late game, if you feel you aren't doing damage to tanks.
