3.28 Strategy Tips

Scarab Synergy: For low-cost farming, use Ultimatum Scarabs of Bribing on white T16 maps. This strategy has shown profits of up to 12+ Divines per hour by focusing purely on completing the 10 rounds and leaving.
Build Requirements: Ultimatum is extremely dangerous. Success typically requires builds with high Freeze chance, Ailment immunity, and high defensive layers like 50k+ Armour or capped Spell Suppression.
Avoid "Conquer the Stones": Generally, nodes that require standing still in small circles are avoided as they make you vulnerable to high-damage monster clusters.
