School Grounds Expedition

School Grounds Expedition uses the Expedition mode's defense format, protecting a payload rather than simply clearing waves for a reward. The defense track opens hard for an Expedition stage, throwing 2x Pelican Curse, 6x Fabric Curse, 8x School Curse, and 1x School Girl into wave 1 alongside Elite-tier enemies from the very start, before settling into a lighter 4x School Curse, 8x Fabric Curse for wave 2. The waves ramp back up through wave 3's mixed Elite spawns to a wave 5 close of 10x Fabric Curse, 7x School Curse, 1x School Girl, and Cursed Summoner itself joining the fight. A parallel Elite Wave track runs the same five School Grounds bosses seen in its Story acts in order: Titan Worm, Mutant Parasite, Centipede Curse, Rope Weaver, and Cursed Summoner.

Two enemy modifiers recur through the defense waves: Sprinter, which trades health for a large speed boost, and Tank, which trades speed for a bigger health pool. That pairing means the wave composition alternates between fast, fragile targets and slow, durable ones, rewarding a team that can flex between burst single-target damage and sustained AoE rather than one pure damage profile.

Cursed Summoner's assault on the payload runs through a two-phase mechanic, hitting for 50 damage roughly every 6 seconds while moving at speed 1.8, noticeably faster and lighter-hitting than Flower Forest Expedition's single-phase Purple Flower assault. A clear rewards ExpeditionMaterial1, this zone's specific crafting material, instead of the flat Gem and Gold payout used by Story and Raid stages.
