House of Valen/A Royal Challenge

==Comprehensive Guide==
Prior to the boss fight on Wave 2, you are given the opportunity to fight Royal Guard & Royal Bowman. It is not necessary to fill up your BB gauge to full since the first few turns in the boss fight will be more focused on using normal attacks. Throughout the boss fight on Wave 2, you will fight Evie along with two Evie's Familiar.
On turn 1, Evie will apply defensive orientated buffs like mitigation, evasion, DoT mitigation, heal when attacked to herself for the whole fight. There is no way to damage her until a certain condition was met. Alongside Evie are the Evie's Familiars, with the top one (Familiar A) being Thunder element while the bottom one (Familiar B) being Light element. 
As the fight progresses, Evie will give a hint to the player on what the condition is to stop Evie from reapplying her buffs again every turn. She will mention "Colors" as the hint, which implies you would need to change the elements of certain enemies via attacking them (a similar battle mechanic used in Palette of the Gods). Since it is not possible to change Evie's element, this means that Evie's Familiars need to have their elements swapped to Dark. The following is the element swap order the Familiars swap to upon being attacked and ending the turn:
 → → → → → 
Note that Familiars can only change elements once per turn, which means that attacking with more than 1 unit will still have the same effect as attacking with 1 unit (Ex: using 2 units to attack a Thunder element Familiar will not change it to Light element at the end of the turn). This means the fastest way to complete the puzzle is through the following sequence of turns:
*Turn 1: Target Evie's Familiar A and normal attack it so that it swaps to Earth element.
*Turn 2: Target Evie's Familiar A and normal attack again so it swaps to Light element.
*Turn 3: Target both Evie's Familiar A and B so their elements change from Light to Dark element.
*Turn 4: Defeat Evie and the two familiars.
Upon both of Evie's Familiar becoming Dark element simultaneously, Evie will no longer reapply her buffs and will now be vulnerable to damage for the rest of the fight.
==Squad Compositions==
===Recommended Units===
*Units without AoE Normal Attack
**It is not recommended to bring units that have access to AoE normal attack due to unintentionally attacking both Familiars at once
