Elemental Powers
A supplement for the BASH! Ultimate Edition RPG that focuses on elemental character themes. It presents dozens of powers across Fire, Water, Ice, Electricity, Earth, and Wind Power Suites, with each entry explaining how to represent the ability using the existing rules. The supplement also introduces new Enhancements and Limitations, additional powers such as Absorption and Trample, guidance for creating custom powers, and rules for random character creation. The material supports both planned character concepts and powers selected at random.
