Conjured Clockwork
You conjure a complex clockwork device on the ground and cause it to slowly spread across the battlefield. The area is difficult terrain. Each creature that enters or ends its turn in the area takes 2d8 slashing damage with a basic Reflex save. A creature can take this damage only once per turn. On subsequent rounds, the first time you Sustain the spell each round, you can expand the radius of the clockwork device by 5 feet.
Heightened (+2) The damage increases by 1d8.
Traits
An action with this trait requires a degree of mental concentration and discipline.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
