Photon Burst (フォトンアクシス Foton Akushisu) is a second-tier Light Elemental spell appear in Luminous Arc 2 and its sequel Luminous Arc 3. It's usable only by Alice in Luminous Arc 2 and later the Archaelon Monster Line in Luminous Arc 3. The spell manifested as a four beams of light that "slash" the target in an area and deal light damage upon them.
It's a variation of Lucia's Lightwave from the original game but in the third game Photon Burst may also inflict paralysis upon the targets as well. It's more powerful than Shine Bullet but more costly and still weaker than Photon Axis.
