Polygon reported that Arcana Unleashed is specifically designed for the 5.5e ruleset, the 2024 Core Rulebooks, and includes what it calls the first major adventure built exclusively for that system. The adventure is set in the magical city of Halruaa, a location that brings a high-fantasy backdrop to the new content.

This marks a notable step in Wizards of the Coast's rollout of 5.5e content, giving Dungeon Masters a ready-made scenario tailored to the updated rules rather than adapting older adventures.

Beyond the adventure, Arcana Unleashed offers player options for higher tiers of play. Bleeding Cool highlighted that the expansion introduces subclasses and spells aimed at tiers 3 and 4, alongside new magical items and evolving relics that grow in power over time. The book also includes factions and feats to deepen campaign customization.

The simultaneous digital and physical release ensures that players can access the content immediately on D&D Beyond while waiting for print copies, a strategy that has become standard for the franchise in recent years.
