You perform a short ritual using the filament of a creature that you have extracted filament from, binding the filament to the internal Flow of another creature. Once complete, the target creature's appearance begins to quickly morph to match that of the host creature as the ritual overrides the target creature's identity, completing after 1 minute.

After the transformation takes place, the target creature flawlessly resembles the host creature. Divination spells that reveal Illusions are ineffective against this spell, and will register the target creature as being the host creature both in creature type and identity.

However, the glamour is susceptible to damage from magical sources. After taking 25 points of damage from magical sources, the glamour will begin to flicker or glitch periodically, possibly rousing suspicion from those that notice. After taking 50 points of damage from magical sources, the glamour fails and the spell ends, with the target creature's appearance and identity reverting back to normal.

The spell lasts until dismissed and will continue to function even in areas of low or no Flow, or anti-magical fields, as it will draw Flow from within you. If either the host creature or the target creature die, the spell ends. The glamour cannot be detected by spells and abilities that reveal illusions or transformations, as the glamour overrides the affected creature's identity.
