The intermediate rank of lightning spirits. Appears in the form of a giant bird that triggers lightning with every wing beat. Takes its name from the Thunderbird of Native American mythology, described as a being that appears with storms. Free and tough in personality, it demands strength from its contractors.
Origin
A sacred bird in Native American mythology governing storms and lightning. In the fantasy world, this mythological being was reinterpreted as the intermediate rank of the lightning spirit tier.
Features
- Giant lightning bird with wingspan of tens of meters
- Summons storms and lightning with wing beats; landing creates an electric shock wave
- Near-sonic flight speed
- Grants the contractor 'Lightning Reflex' â reactions at the speed of lightning
Usage
High-speed reconnaissance, fleet attacks, concentrated strikes on enemy mages. Knights in armor have little chance of survival under a sky where Thunderbird soars.
Weakness
Can be neutralized by grounding the lightning into the earth or through insulating materials. Movement restricted by powerful ice magic.
