Clockwork Eidolon

Clockwork eidolons are living, sentient outsiders whose bodies are enhanced or have parts replaced by constructed metal mechanisms through a combination of magic and precise technologies. Clockwork eidolons that are summoned by clockwork mages hail from a little-known plane called the Plane of Gears. Although these clockwork eidolons are not constructs, it is only through bonding with a clockwork mage that their goal of becoming a true, sentient construct can be realized. As such, it willingly subjects itself to its master’s will in hopes of achieve its true purpose. A clockwork eidolon is considered an outsider for the purpose of what types of spell affect it. Clockwork eidolons have the base statistics as shown on the Clockwork Eidolon Base Statistics table. These base statistics can be modified by the clockwork eidolon’s base form and upgrade pool.


A clockwork eidolon’s abilities are determined by the clockwork mage’s level and by the choices made using its upgrade pool. Table: Clockwork Eidolon Base Statistics determines many of the base statistics of the clockwork eidolon. Each clockwork eidolon possesses a base form that modifies these base statistics. A clockwork construct’s qualities are similar to those described in the Eidolons description block of the Advanced Player’s Guide (see p. 58), except with the following changes.

Hit Dice: This is the total number of 10-sided (d10) Hit Dice the clockwork eidolon possesses.

Good/Bad Saves: These are the clockwork eidolon’s base saving throw bonuses. A clockwork eidolon always possesses a good Fort saving throw and a bad Reflex and Will saving throw, regardless of the creature’s base form.

Armor Bonus: The clockwork eidolon has only an armor bonus, and cannot split this amount between an armor bonus and a natural armor bonus.

Upgrade Pool: The clockwork eidolon uses upgrades, not evolutions to enhance itself. The clockwork gains a number of upgrade points at each level, as indicated on Table: Clockwork Eidolon Base Statistics. The clockwork eidolon’s upgrades otherwise function exactly like evolutions.
