3rd Rematch Battle with Dvesha

The 3rd rematch of the sub Bosses introduced in Rebirth of the Beast King was tough for and interesting to me. Especially I had a lot of fun to figure out routine moves and tactics for the battle with Dvesha.

Tactics

Most troublesome is a stackable all-Elemental debuff, which is cast once in 3 turns and later once in 2. Dvesha's moves change when its HP falls below around 60%. You can not long endure attacks under stacked resistance debuffs nor keep dealing damages while avoiding the repeated debuffs after the turning point. So the tactics I (and many players) took are:

Until the turning point

to receive all-Elemental debuffs only by Amy
to chip off HP (for 10 minutes)

After the turning point

to utilize Amy's VC, SPD and PWR buff, in Another Force

Amy's SPD buff also guarantees the first moves of the party against the enemy by switching always with Mariel when at sub and gives a good chance to have party members protected by Mariel's VC in the next turn.

Tips for a Stable Battle

SPD of 198 or higher
P.DEF of 310 or higher (except Amy)
Mariel with Cruel Angel or Toto Staff

Please skip to 10:45 once you check the first 7 turns (a set of moves).

*Use Exquisite Blossom upon max stack (3) of Spirit Petals

The stack indicator at the INT buff icon helps you being aware of which turns you are at.

2 shown in the indicator means that you are at turn 4 where Amy should receive the debuff.
4 means at turn 7 where Mariel should receive the magic attack.

HP60% Turning Point at 10:45

Immidiately after the Boss' HP below around 60%, it changes the move of that turn to Eruption (Er): Buff/Debuff Removal of only itself + all-area Non-Elemental magic attack. Then its moves are changed as described below.

Remarks

Under the settings at the time of JP ver. 1.7.5 release, the action order of Eruption (Er), a magic attack and buff/debuff removal was set reverse so either Aurora Force or INT debuff was meaningless in mitigating damages by the magic attack. Now as shown in the clip, both elemental buff and INT debuff are useful, and I hope the change be adopted in the Global version from the beginning. If not, Cruel Angel's Staff or Toto Staff with enough upgrade would be necessary for Mariel.

*Including badge adjustment. Claude's SPD around 200 is better to avoid overtaking Mariel.
