Mental Mirror

is a mental mutation that allows a creature to reflect mental attacks back at their source.

This mutation grants the "Mental Mirror" passive ability. Based on Mental Mirror's level, the creature's effective MA will increase, allowing them to better resist all checks that use MA. For certain attacks, the damage as well as effects will also be reflected back at the attacker if the attack fails to penetrate the target's MA.

If Mental Mirror's effects are applied to an incoming attack, it will be placed on cooldown for 50 rounds. It will not apply its bonus MA or reflect attacks while on cooldown.

Things affected
The following mutations can be reflected by Mental Mirror if it fails to penetrate: Everything else that checks against MA will also have Mental Mirror's bonus MA apply (and thus put it on cooldown), but nothing happens if there are no penetrations. This is a non-exhaustive list due to the large swath of attacks that uses MA to check success:
 * Confusion
 * Sunder Mind - Successfully reflecting a damage instance of Sunder Mind will reflect it back at the attacker and will immediately end an ongoing psychic battle.
 * Teleport Other
 * All other types of mental damage, such as psionic weapons
 * Domination
 * Proselytize
 * Anything that inflicts Terrified
 * Syphon Vim

Formulas
The following formula is used to determine MA bonus based on mutation level.

Advantages

 * Low cost at character creation
 * Only way to increase MA that is not willpower related.
 * Reflects certain mental attacks if they fail to penetrate

Disadvantages

 * Very few reflect-able attacks
 * MA bonus scales slowly
 * Only protects against one attack before being placed on cooldown
