Mythic contingency companion spell clarification

In mythic contingency it states you may place a contingency on other people, but only once, unlick yourself, where it can be several times with mythic.

My question is can I place a personal spell as a contingency on another person, or must it be another target? I believe I can place a mirror image on myself with contingency, but can I place it on others?

Mythic Contingency does not change the type of spell that can be used as a companion spell, but it does change that the companion spell affects the target of the contingency spell instead of yourself.

So, yes you could cast mirror image as the companion spell, and it would affect the creature you cast mythic contingency on.

No, I don’t think you can.

Mythic contingency changes the range of the contingency from personal to touch but it doesn’t change the range of the companion spell. It would still have to be a spell you could normally cast on that target.

Still makes for tons of useful options. Invisibility or displacement would work, just to name a couple of obvious defenses.

You can cast this spell on yourself or another willing creature as if the spell had a range of touch. A companion spell placed on another creature must be a spell from you, not from the creature, and affects that creature when triggered. The target can have only one contingency spell upon it at a time unless it also knows mythic contingency. The number of companion spells you can have on yourself is equal to 1 + half your tier.

Mythic Contingency specifies you can cast mythic contingency on a willing target as if mythic contingency had a range of touch. The “This spell” refers to mythic contingency not the companion spell.

The spell to be brought into effect by the contingency must be one that affects your person and be of a spell level no higher than one-third your caster level (rounded down, maximum 6th level).

Mythic contingency does not mention changing the requirements for the companion spell, so that means the spell must be one that affects your person. As the second bolded part of the first paragraph shows the companion spell affects the creature the mythic contingency was cast on.

⇝Contingency:K6 and others. Contingency is Range:Personal and Target:You.
The companion spell targeting of one that affects your person is pretty wide and includes personal and touch spells (you are your own ally). Many GMs also take this to mean the spell cannot affect others, for example a 0 range Fireball would not be allowed although it affects the target of the contingency. The companion spell's Spell Level is limited.

The Mythic Contingency expands the casting of Contingency to Range:Touch so you can cast the spell & companion spell on another. They limit companion spell selection to the caster's spell slots to exclude wands, magic items, SLAs, etc. However, it doesn't change the companion spell Range (as it says "this spell") and thus that excludes personal spells as options on another creature. {Mirror Image:I2 is Range:Personal} TBH Mythic always involves some GM interpretation so YMMV.

Familiars have Share Spells with their master and that creates a loophole for them.

Commentary - this is mostly a "hail mary!" spell for when a creature is in trouble or an effect the creature can "use activate" without expending an action. IMO it should always be defensive. Phrasing can be tricky as spells cannot see into the future so KISS & SMART criteria is best here. There are threads on Contingency companion spells.

⇝Contingency:K6 ... Many GMs also take this to mean the spell cannot affect others, for example a 0 range Fireball would not be allowed although it affects the target of the contingency. ...

At casting Targeted spells can just affect one target (the target of the Contingency). Area of Effect spells don't have that option.

A spell “that affects your person” is not the same thing as a personal range spell.

Displacement and haste both affect your person, even though neither is personal range. Summon monster III does not affect your person.

Mythic contingency does not mention changing the requirements for the companion spell, so that means the spell must be one that can affect your person and that you can ordinarily cast on the target (so no personal range spells).

You can cast this spell on yourself or another willing creature as if the spell had a range of touch. A companion spell placed on another creature must be a spell from you, not from the creature, and affects that creature when triggered. The target can have only one contingency spell upon it at a time unless it also knows mythic contingency. The number of companion spells you can have on yourself is equal to 1 + half your tier.

You forgot the second bolded section.

No, no I didn’t. I cast mythic contingency on my ally and cast invisibility on her as the companion spell. Contingency triggers and my ally becomes invisible. It “affected that creature when triggered.” I would love to cast mirror image on my ally as the companion spell but I can’t because it is a personal range spell.

The part you are forgetting is that mythic contingency changes the range of contingency from personal to touch but doesn’t change the range of the companion spell. Which means it has to be one that you could ordinarily have targeted on that creature.
