Heritage Golem (2x)
The Heritage Golem grants itself framed buffs after its attacks. They can delay you, giving themselves more turns and more opportunities to break you. Their recast becomes more deadly against a broken target.
Their recast is an AoE BRV + HP Attack which progressively gets stronger. Their framed buffs can be dispelled but is not a necessity.
Wyerd (1x) Fire Weak, Ice Resist
Gigantoad (2x) Ice Weak, Water Absorb
The Wyerd can swap BRV with you so make sure you are prepared to shave a large BRV amount before their next turn.
The Gigantoads can inflict poison and frog (making you do 1 BRV DMG for 1 turn). Apart from those debuffs, nothing much to look out for on this wave
Debuffs Inflicted: Poison, Frog
Bastion Giant (1x)
The Bastian Giant is immune to the Frog debuff, so you can't use Yuffie to throw the debuff back from the last wave. It can inflict generic status down debuffs and buffs itself with ATK & SPD Up
It turns red for one (1) turn and increases ATK, DEF, & HP DMG dealt. You can handle this with damage reduction, stun/disable it to prevent it from getting a turn, or summon if you want to be absolutely safe. There is no guaranteed HP attack so just ensure you are protected against the attack.
Debuffs Inflicted: ATK/iBRV/DEF/SPD Down
Might Eater (1x)
Small Might Eaters (2x)
When the enemies first get a turn, your max HP is lowered. It can buff itself with ATK/iBRV/SPD/DEF Up. It has nasty HP attacks. At certain HP thresholds, it will unleash Absorb Energy, which is a BRV Gain + Absorb all of your BRV + AoE HP attack.
You can handle this with damage mitigation or don't give it turns at all with burst, delay, and summon.
Debuffs Inflicted: Sap
