Freeze finger

Flog, Freeze Finger, Ice Storm, Geyser and Drown are attack weaves that
manipulate water to wound a foe. Drown is the strongest, followed by Geyser,
then Ice Storm and Freeze Finger. Flog is a weak weave.

Because Flog requires so little One Power skill, it is among the five
‘cantrips’ often used by channelers to improve their strength in the spheres
of the One Power (along with Burn for fire, Airclub for air, Shatter for
earth, and Cure Light for spirit).
