Overview

This is a Low Life Arc build played on the Gemling Legionnaire, the creator’s “Voltaic Nemesis” setup for the 0.5 Return of the Ancients / Runes of Aldur league. Arc is a chaining lightning spell that hops between nearby enemies, which makes it a natural fit for a caster that wants to walk through packs and let the lightning do the clearing. The Gemling Legionnaire is chosen here for its gem-scaling identity, letting the build push extra levels and quality into its skill and support gems to squeeze more damage out of a single core spell.

Running the build at Low Life means reserving most of your life pool and leaning on a large energy shield buffer instead, which unlocks Low Life-only scaling and reservation efficiency at the cost of a more demanding gear setup. The result is a spell-caster template aimed at comfortable, high-throughput endgame mapping.

Pros & Cons

Pros

  • Arc chains between enemies for smooth, low-effort pack clear
  • Gemling Legionnaire scales a single skill hard through extra gem levels and quality
  • Strong endgame mapping throughput once the Low Life shell is online

Cons

  • Low Life setups are gear-gated and not friendly as a fresh league starter
  • Building a reliable energy shield buffer takes investment before the build feels safe
  • Single-target relies on stacking damage rather than a dedicated boss combo

Key Skills

  • Arc — core chaining lightning spell that handles clear and general damage
  • Supporting reservation, curse and utility gems round out the Low Life shell (see the source for the exact links)

Gear & Anointments

The build is built around a Low Life energy shield base with heavy investment into gem levels for Arc. The creator maintains a full written guide (“Voltaic Nemesis”) with the exact gear, gems, jewels and passive tree; specific uniques and anoints should be confirmed against that source rather than assumed here.
