From publisher blurb:
For many a seasoned adventurer and explorer, magic can become, whilst still a useful tool, boring. You know what a certain spell is effective for, or how potent you need to be to use the spell found on a scroll.
The Spell Options series is a way of tweaking existing spells without using feats. You can change the colour, make the spell weaker and thus easier to cast or make them more powerful but unstable.
This volume focuses on the famous, or should it be infamous, Fireball.
