Spellmaster's Ward
You create one or more glowing protective runes that revolve around you. For each additional action you use when Casting the Spell, increase the number of runes you create by one, to a maximum of three runes for 3 actions.
When you next take damage from a spell, a rune is expended to prevent 2d6 + scaling untyped of that spell's damage. If damage from the triggering spell remains, additional runes are expended until the damage is completely negated, or until all runes have been spent, whichever comes first.
Heightened (+1) Each rune prevents an additional 1 damage.
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.
