Rules & Sources

What MMAid Uses

MMAid reviews characters using Mutants & Masterminds 3E mechanics together with the adopted house-rule layer used in CtrlAltDefeat games. The automated review is a gameplay aid; the Game Master still has final authority over approvals, exceptions, and table rulings.

Adopted House-Rule Source

Freedomverse House Rules & Clarifications

This is the original house-rule reference used as the basis for many of MMAid's character-review restrictions and GM-review checks. MMAid uses an adopted CtrlAltDefeat rule set and does not automatically apply every Freedomverse setting-specific rule.

d20HeroSRD — Action & Adventure

A fast public reference for common M&M 3E gameplay rules such as action types, attacks, defenses, damage, grabs, combat maneuvers, recovery, cover, concealment, and other in-session rules.

How to read MMAid results Correction Required: a confidently identified rule conflict. GM Review: the build may be allowed, but the adopted rules call for approval or additional scrutiny. Unable to Validate: the upload did not provide enough trustworthy data; do not change the character blindly.
Privacy & behavior

Local-first

The file is read using browser APIs. Hero Lab .por archives are decompressed locally. MMAid does not send the character to a server. This page performs work only when you choose a file; it does not poll or scan in the background.
