Blk Magic is one of the four main skillsets found in Final Fantasy X. The abilities found is the Blk Magic skillset are designed to inflict damage to opponents, however unlike abilities in the Skill skillset, they inflict damage magically instead of physically. All Blk Magic abilities cost MP to cast except Osmose which is designed to increase the player's MP stat.

Most Blk Magic abilities are found in the Lulu section of the Sphere Grid, with only three of the 19 not being found on her there. The two Blk Magic abilities found on the Wakka section of the Sphere Grid, Drain and Osmose, are abilities designed to drain stats from the target, HP and MP respectively. The ultimate Blk Magic, Ultima, is found on the Kimahri section of the Sphere Grid. Most Blk Magic abilities are Rank 3 abilities, however the abilities in the Wakka section of the Sphere Grid are only Rank 2, while the two non-elemental spells are of considerably higher Ranks.

The Blk Magic skillset is special among the other four core skillsets is the abilities that Lulu has learned on the Sphere Grid control the abilities she can use during her Fury Overdrive skillset, similar to how the Grand Summon Overdrive skillset for Yuna works. Most of the Blk Magic abilities learned on the Sphere Grid can be found on the Overdrive skillset.
