How Enchantments Work in Slay the Spire 2

Enchantments are permanent buffs applied to cards during a run. Unlike upgrades, enchantments do not go away and can be stacked.

Deep Research: When you visit the Enchantress, you can pay gold to add properties like 'Retain', 'Ethereal', or 'Lacerate' to any card.

Deep Research: To encounter an Ancient, you must solve a map puzzle in Act 2. They possess 2x health of a regular Elite and have unique status effects.
