Best for: 2P or 3P parties lacking a frontliner.

Before we talk about cards, you need to understand the Prism’s unique identity. The Prism does not have a "role." It assumes one.

The Prism utilizes four Modes (represented by four different miniatures or a swappable dial, depending on your table’s organization). Your hand of cards is static, but your Mode determines your stats, your movement, and your innate bonus. frosthaven prism guide

Critical Rule: You switch Modes by playing cards that feature the "Realign" keyword. Most of your powerful "Loss" actions also force a Mode change.

The secret to the Prism is anticipation. You must know what the next two rounds look like. You cannot play the Prism reactively. You must predict the monster ability cards before you flip them. Best for: 2P or 3P parties lacking a frontliner

Furthermore, the Prism interacts with Glimmer tokens. You generate these by hitting specific elemental thresholds or using specific top actions. Glimmers sit on enemy hexes or empty hexes. When you "Trigger" a Glimmer, you usually perform a free attack, heal, or push.

Pro Tip: Think of Glimmers as landmines you are legally allowed to place. A Level 5 Prism can lay three Glimmers in a hallway and then use a single Move action to detonate all of them. Critical Rule: You switch Modes by playing cards
