Farming with this champion can be very hard with karma in the early stages of the game, since she has not much attack damage for her basic attacks so try to have some control over the use of your mana to be able to use Qs on the minions and kill them 3-3 once they don't have more than 30% hp.

Don't hesitate to use your ultimate to boost your E in order to shield your teammates and you also combo with an item that you buy called 'ardent Censer' which boosts the amount of shield that your teammates get from you.
