Recursion

Recursion is a common Defect skill that evokes your next Orb and then immediately re-channels the same Orb type for 1 Energy. This means you get the evoke effect of an Orb (its triggered burst effect) without permanently losing the Orb from your queue — it refills the slot with a fresh copy of the same type immediately. It's a repeatable Orb evoke that maintains the Orb count.

Recursion is particularly powerful with Dark Orbs that have accumulated large amounts of stored damage — evoking a fully-charged Dark Orb and immediately refilling the slot starts the accumulation again from scratch. In Lightning builds, it triggers the evoke burst while maintaining the passive damage Orb. It requires positioning management (evoking removes the leftmost Orb) but rewards careful play. Upgraded, it costs 0 Energy instead of 1, making it a completely free Orb-evoke-and-replace.
