Offlane Support. Constantly harass the enemy with autoattacks and Nether Blast but be wary of disables and stuns. Place your Nether Ward in the trees near your own tower, it has a long range and damages enemies when they use abilities. At minute 5, after the catapult enters your lane, aggressively push the lane and take the tower with Nether Blast, which damages towers. Use Decrepify to disarm enemies and make them take more magic damage, but remember that this prevents them from taking physical damage (may annoy your allies). Take Tormentor at minute 20, you are good at killing it. You can channel Life Drain (hold R) to suck your opponents of health or drain your own life into your allies to heal them.
