Etched Sigil
This source rewards channeling: while you cast Arcane Torrent, Disintegrate or Ray of Frost, the damage of Energy Twister is increased and an additional Energy Twister is cast automatically every second. You loose empowered projectiles on the side without ever interrupting the beam.
For the Wizard this is a cornerstone of many channeling builds, because you run two damage sources at once: the beam and the free, auto-cast Energy Twisters. Since the source also brings critical hit chance and Intelligence, it props up your stats directly. Practical tip: keep the channel running as continuously as possible, since the extra Energy Twisters are only cast while you're channeling – every interruption costs you not just the beam damage but also the steady supply of empowered projectiles.
The roll range and the automatic twisters
Energy Twister damage rises by 200 to 250% while you channel. The automatic twisters carry the source's extra damage, so a high roll pays off - a Primal Ancient has the full 250%. Without the bonus, one Energy Twister deals 1525% weapon damage over 6 seconds.
Picking an Energy Twister rune
- Mistral Breeze lowers the casting cost to 25 Arcane Power and turns the damage to Cold. With Ray of Frost as your channel, beam and twisters then share one element.
- Gale Force makes enemies hit take 15% more Fire damage for 4 seconds - interesting when your beam deals Fire through Flame Ward on Arcane Torrent or Convergence on Disintegrate.
- Raging Storm merges two colliding twisters into a tornado dealing 3200% weapon damage over 6 seconds.
- Wicked Wind makes the twisters spin in place instead of traveling, for 835% weapon damage.
- Storm Chaser stores up to 3 Lightning Charges that only a Signature spell releases.
Stats on the source
Intelligence at 626 to 750, 8.0 to 10.0% Critical Hit Chance and a small damage bonus are fixed. Also look for Energy Twister damage, Arcane Power on Critical Hit, maximum Arcane Power, Area Damage and Cooldown Reduction. The source is often combined with Ranslor's Folly, Halo of Karini, Convention of Elements, The Twisted Sword and Valthek's Rebuke. The flavor text quotes Zoltun Kulle: the arcane realm gazes back at whoever stares into it long enough.
