Tips

 * See testimonials and discussions.
 * On turn 1, Elafikeras will give your party MP refresh (~900 MP per turn for 8 turns), and will start attacking properly from turn 2 onward.
 * This battle is a simple damage race. You have 8 turns to defeat Elafikeras before it rages. Note that the mission requires you to clear within 7 turns.
 * If you cross multiple thresholds at once, all the conditional attacks will trigger together.
 * Once it rages, it will use AoE death, MP drain, 99999 damage to party and fully heal itself every turn.
 * It is vulnerable to disease, reducing its stats by 10%. In essence increasing your damage done by 10% and reducing your damage taken by 19%. You can use Toxic Rain to inflict disease with a high chance.

Survival

 * With a proper setup, dedicated healer is not necessary.
 * You can either use a cover tank or a very high breaker. Coupled with a bard, that will be enough to mitigate damage taken.
 * For cover tank you can use Warrior of Light or Basch as they also have ATK/MAG break. Rotate between cover and break.
 * Use Mechanical Heart to heal most of the damage taken.
 * Alternatively, you can use a unit with very high break like Tim, 9S, or Knight Delita, any of the units listed here.
 * To inflict disease, Toxic Rain or 9S' LB will work.
 * A strong bard like Roy, Ramza (Awk), or Lunera (Awk) will heal the remainder of the damage and buff your party.
 * It uses Charge every turn, which is physical AoE damage, and on 75% and 50% threshold it will use a stronger AoE ability once, which can be either physical or magic damage. If you damage it with a magic spell on that turn it will use a physical damage, otherwise it uses magic damage. This has to be a magic spell and not an ability with magic damage.

Damage

 * With 2 slots taken for survival, the rest 4 slots can be dedicated to damage.
 * You can use either physical or magic attacker, but due to its stats, magic damage will deal three times more damage than physical damage, and it is weak to wind.
 * Recommended wind magic attacker:
 * 5★: Barbariccia, Lunera (Awk)
 * 4★: Hope (Awk)
 * 3★: Shantotto
 * Even without wind damage, it doesn't take much to defeat Elafikeras. As a point of reference: A Blossom Sage Sakura with 1000 MAG (counting buff) dual-casting Quick Final Thunder every turn, capping chains, will deal between 70,720,000 - 83,200,000 damage in 7 turns, without any imperil.
 * 2 Shantotto and 2 Hope (Awk) with 400-650 MAG are enough to defeat this trial, see this video.

Bug

 * "Multi-Horn" may cause an AoE physical cover to not trigger.
