====Mega-Stunt Construction and Costs====

Each Mega-Stunt must be individually worked out with the GM, based on the permission above. Also, each Mega-Stunt comes with a related Weakness or Cost. For a Weakness, for instance, the Fiery Adept can project bolts of fire, but takes damage from attacks with water. For a Cost, use of the Mega-Stunt comes "at a cost" - an immediate minor cost that can be determined by the GM, or simply take the form of a free compel from the GM on the character's Archetype or Curse.

Mega-Stunts typically consist of combat superiority (+2 attack or +1 armour); automatic success (in a specific Overcome action or an opposed roll against an opponent without a matching Mega-Stunt); immunity (to a particular attack or skill effect); or enhancement (to a normal stunt). However, other types can be worked up in discussion with the GM.

The Evil Hat Fate Core Stunts list (http://evilhat.wikidot.com/fate-core-stunts) has some inspirational ideas for Mega-Stunts - especially those with tiers or that require other stunts. Broadly, a Mega-Stunt is equivalent to the kind of stunt that requires another initial stunt - e.g. "Safe Fall (requires Acrobat)" - but does the same in one go.
