Glade

It takes 6 Scratches to have enough breath to use Eliminate, so in the first spawn you will be capable of using Eliminate. Just make sure that your first spawn is not comprised of a Wartoad, or of 3 physical attackers (Toridae, Shellions, Scythe and Sickle Kamaitachi). You should be able to get to speed without being defeated.

Once your breath is up, for the next batches of enemies, have your trainer use Rally on itself on the first turn, then Eliminate the enemies. Only Mossy Cerdae and Brilliant Psywurms require a Scratch+Eliminate combo; therefore, if a spawn is entirely these, you don't need to use Rally.

You'll want to target Scythe Kamaitachi and Venomous Toridae first, followed by Salve Kamaitachi and Wetland Unicorns due to their Contuse. After that, just go by physical attackers followed by magical attackers. However, because of elemental weaknesses, use the guide below to help you figure out who to attack first.
