PSA: Mage Supports
Don't touch the minions newbie. Your spellthief item gives you gold for damaging towers and enemy champions. In general if you don't have any tier of the relic shield do not bother ever touching the minions during laning phase. Only time it is acceptable is if you're pushed under tower and you know how to control the waves so your adc can last hit. Please and thank you, sincerely anyone who plays adc and is losing farm because of their support.
E while keeping the enemy at bay. No one complains over 1 - 2 cs, when I'm keeping them alive.
