Black Luna

Only available on Zelgius and the Black Knight, Black Luna is a non-inheritable skill known as one of the deadliest in the game. It's effect of reducing enemy Defense and Resistance by 80% means that it is capable of cutting through tanks with ease, and with a charge time of only three it can be readily used, sometimes multiple times. It can be compared to the regular Luna which only reduces Defense and Resistance by 50% for the same charge time.

Being only available on two characters means that Black Luna's synergies align closely with that of Zelgius and the Black Knight. These units tend to build towards activating Black Luna as quickly as possible, and with as much power as can be granted. Steady Breath combined with the Quickened Pulse seal lets Black Luna activate after just one attack, but only once per round. Wrath is a great skill to use with Black Luna, boosting it's damage even further and making subsequent activations easier. Bold Fighter is common on both Black Luna users, and can trigger the special with Quickened Pulse or provided the foe counterattacks.

With a charge time of only three and a whopping 80% Defense/Resistance ignore, Black Luna is one of, if not the most fearsome specials. Guard is one of the best answers to Black Luna, as it delays the special from activating.
