Description
Luck Up materia is a 
Complete Materia in Final Fantasy VII Remake and "Episode INTERmission". When equipped, it increases the user's 
Luck by a percentage: 10% at first level, up to a 50% increase at level 5. Luck Up materia can stack, up to a +100% boost, meaning two max level Luck Up materia can be equipped per character. The luck attribute increases a character's chance to perform a critical hit, or to successfully steal an item.
Obtained[]
Top score.
Getting the top placement in the darts minigame in Seventh Heaven scores a Luck Up materia from Wedge, the previous top scorer. Wedge will yield the prize when he is at the Seventh Heaven in Chapter 4, "Mad Dash", when all of Avalanche gather there as part of the story.
A Luck Up materia is one of the rewards for the squat minigame in Chapter 9, "The Town That Never Sleeps". Beating Jay for amateur level will reward it.
In INTERmission, Luck Up is sometimes sold by the Junk Shop in the tunnel in the northern section of the Sector 7 Slums for 1000 gil, whose wares change depending on quest and Fort Condor progress.

Use[]
The Luck Up materia provides a percentage boost to a character's luck attribute, and multiple can be equipped to boost up to 100% of a character's base Luck. Higher luck boosts a character's chance of performing a critical hit, or successfully stealing an item.
Equipping Luck Up materia on a character with steal materia boosts their chance to steal while also boosting their critical hit chance, making it a good use for a character who has a spare slot. Beyond this, Tifa and Barret both benefit most from high luck because their abilities and attacks are based around multiple hits, and increasing their chances to score a critical hit means they could perform multiple critical attacks. Tifa and Barret also demand few materia slots, as they are less likely to equip as many 
Magic Materia. Though Cloud performs fewer hits, his attacks already hit hard, and so making them critical hits more often can further improve his damage, while Aerith can still benefit from a critical hit boost even if she is less reliant on damage from her weapon, if she has the slot to spare. Both characters are normally better off with other materia, however.
Ultimately, Luck Up materia is a luxury choice. It can be equipped on a character with the slots to spare, and will provide a decent increase to their damage output, or chance to steal. It will not make or break a character, and there are other materia that can make better use of a slot.
