Battlefield Details

 * Buff and TP do not wear on entry.
 * No exp loss.
 * 30 minute limit for both parts.
 * Sanctus Rosary grants immunity to doom (see below).
 * You fight against Klara (1st part) and against a demon (second part).
 * If the battlefield is failed, the key item will no longer be in your possession, but you can immediately re-enter without it. No zoning/key items required.

Klara:
 * Recommend buffing fully outside before entering as buffs do not wear on entry.
 * Zeid fights with you. He will run in and engage shortly after entering (random time, possibly immediately).
 * Zeid's HP can drop quick, if he dies, the battlefield ends in failure.
 * Zeid can be buffed including protect, shell, and haste.
 * Klara often double and triple attack followed by a weaponskill.
 * Klara uses the weaponskill Savage Blade.
 * Klara uses the weaponskill Darkring Blade which is an AoE knock back with heavy damage and curse (drops maxHP by about 50%).
 * Klara uses the weaponskill Templar Blade which is an AoE with heavy damage and petrify.
 * Klara seems to have a hate reset, but need confirmation and what weaponskill causes the hate reset.
 * Klara must be defeated at 0% to reach the second fight. The fight will not end at an earlier percent.

Marquis Amon (Demon)
 * Zeid does not assist with this portion of the fight. You can take as much time as you need (within the 30 minute battle limit) to recover before engaging Marquis Amon.
 * Marquis Amon has relatively weak defense compared to Klara.
 * Marquis Amon can cast tier 4 single target and tier 3 -aga elemental magic. Stun recommended.
 * Below 30% (roughly), he will use a TP move which draws in and does moderate damage. Anyone without the Sanctus Rosary equipped will also receive the effect of Doom.
