Flameblade

Burn, Flameblade, Lightning, Firestorm, Fire Bolt, and Hellfire are attack
weaves that manipulate fire to wound a foe. Hellfire is the strongest (and
is the sole remort weave of this group), Firestorm next strongest, then
Firestorm and Lightning, and both Flameblade and Burn are fairly weak.

Because Burn 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 Flog for water, Airclub for air, Shatter for
earth, and Cure Light for spirit).
