Level 39 Affliction Warlock twink build

This is a 30-point Affliction twink built around the level-39 breakpoint: instant Corruption, Fel Concentration for reliable Drain Life and Drain Mana channels under attack, Grim Reach, Nightfall, Siphon Life, improved Curse of Exhaustion, and finally 5/5 Shadow Mastery. You give up Shadowburn burst, but gain far better control, sustain, and Shadow DoT pressure.

The gear leans toward the PvP toughness knee rather than pure glass-cannon spell power. The provided curve shows balance 40 at 1140 HP from gear for only a 5% throughput loss; the next step to balance 50 adds just 210 HP for another 3% throughput loss, so this set stays in the efficient stamina-heavy range while keeping strong Shadow damage. Lucky Fishing Hat, Dragon’s Blood Necklace, Pads of the Venom Spider, Silky Spider Cape, and Robes of the Lich are the key survival pieces. Damage comes from Staff of Jordan, Underworld Band, Stormcloth Gloves, Defiler’s Cloth Girdle, Necromancer Leggings, Defiler’s Cloth Boots, and Lady Falther’ess’ Finger. Use Highlander’s equivalents if Alliance.

Open with Demon Armor up and Shadow Ward when relevant. Use Amplify Curse into Curse of Agony for pressure, or into Curse of Exhaustion when you need to kite. Keep Haunt, Corruption, and Siphon Life rolling, then Fear to create distance or force trinkets. Drain Life when low, Drain Mana into healers/casters when you have breathing room, and Shadow Bolt mainly during Nightfall procs or hard-CC windows. Tidal Charm is your kill setup or emergency peel; Rune of Perfection helps your spells bite through resistance.
