Wild Surge Generator

A wild surges is a random magical effect which can sometimes occur when casting magical spells. Wild surges add random surprises that can enhance role playing games and stories. These surges can lead to very interesting situations. Some wild surges are beneficial, others are dangerous, and some are comedic. References to the spell's duration/effects refer to the original spell attempted by the caster.

Wild Surge Table

Below is a table of wild surges. Roll a 100-sided die and select the chosen wild surge. Anyone running a campaign (like a Dungeon Master), or telling a story, should consider our list of wild surges as a source of ideas, and should not be bound by the results of their die roll.
