Reset Tonberry Hate via "Everyone's Grudge" quest every two fights to mitigate Everyone's Wrath/Revenge/Virulence. As long as you are calling for help on the adds every run you should not need to reset hate after every run.
*I believe the remaining Tonberry Adds have LoS (Line of Sight) aggro on the Rascal so pulling him to the far back corner behind the pillar will prevent the other adds from linking/aggroing.
Tonberry Adds:
Bozzetto Rascal (SMN): Rascal is the first enemy and the remaining Tonberry's will spawn after a certain time of the Rascal being aggroed. Summons water and ice elementals. Can use Astral Flow multiple times. Spawns Monarch at center of arena after being defeated. I believe the remaining Tonberry Adds have LoS (Line of Sight) aggro on the Rascal so pulling him to the far back corner behind the pillar will prevent the other adds from linking/aggroing.
Bozzetto Defiler (BLM): Uses Manafont.
Bozzetto Slicer (NIN): Uses Mijin Gakure.
Bozzetto Chaser x2 (THF): Uses Perfect Dodge
Have high Light Resistance
Bozzetto Monarch:
Spawns after the Rascal is defeated with a random job of either DRK,MNK,THF,WAR with their corresponding 1 hours.
TP Moves:
Light of Condemnation: Single target Gravity, Bind, TP reset.
Always proceeded by either Vertical Slash or Lateral Reap creating a Distortion Skillchain.
A Bozzetto Shade will then appear to perform a Sneak Attack on the target closing a Darkness Skillchain.
Turn towards the Shade to avoid Sneak Attack damage.
Vertical Slash: Damage and accuracy down.
Lateral Reap: Damage and -75% defense down.
Everyone's Wrath: Single target damage equal to Tonberry Hate x20
Everyone's Revenge: 25'+ AoE damage equal to Tonberry Hate x100
Everyone's Virulence: 99,999 damage regardless of Tonberry Hate.
Sigh: 400 Evasion buff.
It's worth noting that Tonberries can't seem to overwrite Distract III with Sigh. RDM is excellent this month.
Throat Slice/Slash Vitals: Critical damage and hate reset.
Words of Bane: -50% HP/MP Curse.
Earthern Armor, Sentinel's Scherzo, and Migawari: Ichi do not affect Everyone's Wrath/Revenge/Virulence.
