Magi of Tom has created a sample Flambeau who is focused in lightning. That’s a great character concept. It reminded me of a love for lightning spells, especially thematic ones – like the ball lightning which surrounds Shaman characters in WoW. So extending on the two other lightning based blog posts with spells (a ward and improved lightning bolt spells) – here is a lightning shield.
Shield of Crackling Lightning
Creo Auram / Rego 35, R: Personal, D: Diameter, T: Individual
The caster is surrounded by webs of interlaced lightning which will not harm them but will damage anything directly interacting with their body. The lightning inflicts +30 damage.
(Base 5, +1 Diameter, +4 unnatural, +1 Rego protection)
