The enemy's workaround to the magic ban: non-magical stones packed with fire and poison, dispersed by standby mages.
Because Phase One Combat forbids offensive magic, enemy stones bounce off the FUPA's shield, but the attackers found another route. Flames burst around the half-circle shield that encompasses the grounds and thick smoke starts to billow: poison. The projectile was not magical, Carl notes, but they still figured out how to use chemical warfare.
Team Retribution anticipated exactly this, and several mages stand by casting spells to dissipate the clouds. The barrage is only a prelude, since Carl knows that once the 180 hours expire the Artillery Batteries will begin throwing stones enchanted with devastating spells, which is why destroying them is the priority. Elle adds from the Southern Front that she suspects the rocks are cover for something else entirely.
Rocks bursting into flame against a shimmering dome, thick clouds of poison smoke rolling across the compound as mages cast dispersal spells.
The enemy's legal loophole around the offensive magic ban in the war's opening barrage.
