Spellcasting behavior[]

Thunder Spirit is more likely to use powerful spells in thundery weather or on Thundersday. The delay between its spells can be reduced by having higher Summoning Magic skill, wearing Summoner's Spats, or summoning the spirit in its matching day and/or weather.


Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide).

The word spirit derives from Latin spiritus, "breath", has many meanings most relating to a non-corporeal substance contrasted with the material body. The word is often used metaphysically to refer to the consciousness or personality. The notions of a person's spirit and soul may overlap, as both are understood as surviving the bodily death in religion and occultism. "Spirit" can also have the sense of "ghost", i.e. a manifestation of a deceased person. The term may also refer to any incorporeal or immaterial being, such as demons or deities.
