How to farm Herba Mystica in Blueberry Academy?

In Pokémon Scarlet and Violet, you can get Herba Mystica after completing some Tera Raids; some reward one specific kind of Herba Mystica, others none at all, and a few of them can give you Herba Mystica of all kinds.

Herba Mystica only becomes available only in 5-Star and 6-Star Tera Raids; even if you get the chance to explore the Terarium early, you still need to complete the main story up to the game credits for 5-star ones and do the tournament and a few other raids for the 6-star raids.

The Following Tera Raids can reward you with Herba Mystica of all kinds:

5-Star Raids

• Lapras
  • Special Defense is higher than Physical; moves may induce Sleep and Freeze.
• Kingdra
  • Defenses balanced, moves may induce Sleep.
• Malamar
  • Physical Stats higher than Special Stats may use the move Topsy-Turvy, which inverts your stat Changes (+6 Attack becomes -6 Attack).

6-Star Raids

• Galarian Slowbro
  • Special Defense lower than Physical
• Alolan Muk
  • High Physical Attack and Special Defense, Low Physical Defense, and some of its moves may poison your Pokémon.
• Lapras
  • Special Defense is higher than Physical; moves may induce Sleep and Freeze.
• Kingdra
  • Defenses are balanced, and moves focus on special damage.
• Porygon2
  • Higher Special Stats and moves may cause Burn, Freeze, Paralysis, and Confusion.
• Malamar
  • Physical Stats higher than Special Stats may use the move Topsy-Turvy, which inverts your stat Changes.

There is no guarantee you will get any kind of Herba Mystica after the raid, but these raids have a chance to give Herba Mystica of all five kinds.
