Aura Masking

AURA MASKING
Type: M Action: Free
Range: Self Duration: Sustained

Sometimes a spirit doesn’t want someone to assense its natural aura. This power functions like Mask / Physical Mask (p. 326, CRB) and Extended Masking metamagics. Use the spirit’s Edge in place of its initiate grade. The spirit can also hide its own use of powers on itself within the mask; only a magician who pierces this mask can see the spirit using such powers. A spirit can mask itself to look like another astral being, but it cannot try to pass itself off as a mundane being unless it is attached to a physical body or has the Realistic Form power (p. 198, SG).
