-Lane as long as you can to get enough to buy Tear of the Goddess and your Sorc. Shoes together. As soon as your done that, go back into lane and farm some more.
-In the beginning before the game starts, use your Q three times to get your voidling ready on your next attack.
-Troll with your Q AS MUCH AS POSSIBLE! It takes time to predict your enemies movement. With concentration and practice, you'll be able to land it perfectly.
-When you're ready to take out their heavy hitter/carry, go in this order: E->Q->W->R. If you're dropping them by just your first attack, don't bother casting your other ones unless needed. Only go for the one that your ult is worth using on. Some people would see the Deathfire Grasp as a helpful item but I've tried to use it and always forget to use it when i get it. You're preference.
-While running away if you're being chased, sometimes it is helpful to use your Q so they don't use any of their abilities to catch up.
-Stay back as far as you can in team fights.
-Don't get dead.
