Bug Fables: The Everlasting Sapling

Here is the build I used. I was at rank 25 and had all rank ups invested in Medal Points, and, at that rank, my team had 77 MP and 15 TP. TP and HP will vary depending on side quest completion and how others choose to use the HP potions. Also, I had completed the quest to get the Chomper pet, which gave me an additional 1 damage per turn. Additionally, I had purchased the attack buff seed from the vendor in Defiant Root and gave it to Vi.

Vi (Front)

• Last Attack x2

• Power Exchange x2

• Antlion Jaws

• Poison Attacker x2

• Poison Defender x2

• Weak Stomach

• Eternal Venom

• Miracle Matter

Kabbu (Middle)

• HP Plus x4

• HP Core

• Prayer x2

• Meditation x2

• Reflection x2

Leif (Back)

• Leaf Cloak

Team/Other

• Hard Mode

• TP Core x2

• Poison Needles

The idea with this build is to get Vi poisoned early to have high damage output while also never allowing her to take damage.

Turn order...

1st Turn
Assuming everyone is in the previously listed positions, press B to select Kabbu and use a food item on Vi to get her poisoned. This is best done with a Big Mistake (cook a mistake again to make a big mistake) as she will be poisoned and drop to 1 HP giving her another +4 to her attack from the 2 Poison Attacker medals and the 2 Last Attack medals (for those that don't know, poison will not drop a character below 1 HP.) Now attack with Vi using her Needle Pincer; with the attack buffs it should deal ~18 damage. Finally, use Leif's Bubble Shield Lite on Vi.

2nd Turn and beyond
Use Vi's base attack, which should deal ~10 damage, have Kabbu "Do Nothing," earning him 4 HP and 2 TP for the team, and use Leif's Bubble Shield Lite on Vi. If ever Leif gets low on health and TP is okay, feel free to use Kabbu's turn to heal them up. In the off chance they faint, (unlikely due to the reduced targeting as they are both in the back spot and wearing Leaf Cloak) use Kabbu's Pep Talk to resuscitate them. If Vi goes down, have Kabbu continue to "Do Nothing," and have Leif use Bubble Shield Lite on themself; Miracle Matter will revive Vi after 2 turns with 4 HP.

The boss only has 80 health on hard mode, so it should not take long to defeat them; it should be between 6 and 8 turns.
