Daystar




 * The ultimate skill of one of the original fallen angels. It counters the enemy, and annihilates them. It seems to be compatible with the power of water...


 * "My mother is the Star of Morning, the child of dawn. The star thrown to the Earth shall obtain victory!" - Luka

Daystar is one of Luka’s most powerful techniques, behind Element Spica. When attacked, Luka counterattacks with a dazzling star, striking three times with heavy damage.

In Chapter 3, after Luka finally awakens his angelic powers against Archangel Ranael, Daystar replaces Serene Demon Sword and costs 8 SP to use. However, if the monster does not attack, the skill will not work, wasting a lot of SP.

Once Luka reacquires Salamander, there is a nifty trick with Daystar that results in the enemy's imminent doom. First use Daystar to counter and dish out huge damage, then use Salamander to regain all the lost SP, then use Daystar again, and if the enemy is still alive, Heavenly Demon Revival or Word of Dispel. This combination can guarantee victory in most fights, but some enemies can easily shut down the combo by not triggering Daystar or disabling Luka in some way when summoning Salamander.

Once the seal weakening the four spirits was removed, Undine powers up this skill to Infallible Daystar, making it deal more damage.

Trivia

 * When Luka uses it against Kraken, a counter was not initiated, rather, he used it straight off the bat right after using Flash Kill.
 * "Daystar" is one of the monikers of the Fallen Angel Lucifer, heavily hinting at Lucifina's role as a fallen angel and rebel against the Goddess Ilias.
