0.5.0 Return of the Ancients

The Runes of Aldur league and the final Early Access update before 1.0. Headline changes:

• Two new ascendancies: Martial Artist (Monk) and Spirit Walker (Huntress).
• Runes of Aldur league introducing Verisium Runeforging and the new Runic Ward defence layer.
• Massive endgame overhaul: the Precursor Fortress, a reworked 300+ node Atlas passive tree with per-mechanic sub-trees, Masters of the Atlas, and the new pinnacle boss Arbiter of Divinity (plus two new Citadels).
• ~30 new endgame map areas; Waystones must now be identified before use.
• 13 new Alloy currencies; Greater/Perfect orb tiers made rarer; defence and energy-shield recharge rebalancing; a per-hit ~40k leech-input cap.
