Summon bear shifter
Summon bear shifter is a spell of Bloom, the affinity that Virenna, the Greenmother holds. It is costly and takes more than a single turn to cast. It calls Bear shifter, the two-shaped folk of the deep forest, who come to battle in the bear's shape: slow to fall, and heavy enough in the paw to split armour.
The bear-folk are proud that they carry Bloom. Their wilder cousins, Wolf shifter, carry no affinity at all. The bear, the bear-folk say, is the shape the forest gives to those who guard it; the wolf is the shape of those who only roam it. A lord who casts this spell is asking guardians to leave their forest, and the bear-folk expect to be treated as guests, not hirelings.
Bloom's neighbours, Pyre and Lumen, can reach this spell, though outside Bloom it costs more, fails more easily and calls fewer. A deeper realm calls more. Like every spell pressed into a core since the Age of the First Sealborn, it perishes at the Unsealing.
