Consume
Consume is an uncommon Defect skill that gains 2 Focus and permanently loses 1 Orb slot, then Exhausts for 2 Energy. Focus is the Defect's primary scaling stat — each point of Focus increases the passive and evoke effects of all Orbs. Trading 1 Orb slot for 2 Focus is a meaningful exchange: you can channel fewer Orbs simultaneously, but each one becomes significantly more powerful.
Consume rewards builds that prioritize Focus scaling over Orb quantity. After one or two Consumes, each individual Orb deals more damage (Lightning), blocks more (Frost), or accumulates more (Dark), compensating for the reduced slots. It's most effective in Dark or Lightning-focused builds where a single slot with high Focus outperforms many slots with low Focus. Upgraded, the Focus gain increases to 3 instead of 2, improving the exchange rate and making the slot sacrifice more worthwhile.
