The Echoing Strike Warlock is a true budget powerhouse, built around mechanics that scale with skill synergy, sustain, and debuff control rather than item price. By leveraging spell-based damage that ignores attack rating, Insight-fueled mana sustain, Levitation Mastery scaling, and Life Tap–driven survivability, this build delivers consistent damage and near-infinite sustain even on low-tier bases and throwaway rares. Whether you’re starting fresh, pushing Hell on minimal gear, or looking for a realistic Uber-capable setup without CTA, Torch, or expensive runes, this guide breaks down exactly how the Echoing Strike Warlock succeeds where traditional “budget” builds fall short.
