# Upgrade Direct Item to Mythic (Horadric Cube recipe)

Takes 1x Unique item (non-Iconic; 'Crafted'-tag-eligible) + 5x Resplendent Spark and produces Mythic-quality version of the input item. Diablo IV patch 3.2.1.

## Inputs
- 1x Unique item (non-Iconic; 'Crafted'-tag-eligible) (Cannot be Unmodifiable. Item Power requirement DISPUTED: the PTR-era sources consulted for this entry say 850+; one guide's live 2026-09-19 page says 900+. Level 70 / Torment I+ reported by those same PTR-era sources, unverified live.)
- 5x Resplendent Spark (confirmed by 2 independent live sources (one guide, another guide))

## Output
- Mythic-quality version of the input item - 1:1 deterministic transfer - keeps ALL of the input item's existing affixes, Tempering, and Masterworking exactly as rolled. No RNG on the output.

## Restrictions
- Cannot be used on an Unmodifiable item
- Result carries the 'Crafted' tag; only one Crafted-tag item can be equipped at a time
- Iconic Mythics remain obtainable only as Mythic-quality (cannot be produced by this recipe from a Unique version, since Blizzard scrapped PTR plans for Unique versions of Iconic Mythics)
