The current Eredrim build answer is a counter-focused setup: unlock Eredrim by defeating The Warden at Citadel of Penance, pair the Shell with Great Martyr's Blade, and treat Frost support as conditional context from the available community test. Balance Patch 1 increased Great Martyr's Blade attack damage by 20 percent, but that patch fact does not prove a universal best build or a post-patch DPS number.
