Light & Darkness Powers
This supplement for the BASH! Ultimate Edition RPG adds powers, enhancements, limitations, and character-building ideas focused on light and shadow. It supports luminous cosmic beings, shadowy figures, and characters who manipulate light or dark energy, with abilities such as lasers, radiation, phasing, cosmic travel, solidified darkness, and access to a Shadow Dimension. The volume also introduces Hyper Speed, which uses Speed Stunts within a Panel, and a playtest version of Wizardry for versatile magical effects. New Alterations and Enhancements provide additional options for creating themed characters or generating powers at random.
