This is a another simple birthsign overhaul mod. This mod gives each birthsign a redesigned passive ability and once-a-day power. Each birthsign's ability is based on its description from lore sources, such as The Firmament, and is balanced in-game loosely according to spell effect costs. In other words, if every birthsign was an enchantment or spell, with any negative effects subtracted from the cost, they would all cost about the same amount, with some adjustments for other balance factors. This mod requires the Tribunal Expansion.
