Spinning Staff
You spin your staff with a twirling flourish, attacking two foes and transforming the momentum into magical energy to charge for your next Spellstrike. Make a melee Strike with your staff against one foe and then a second melee Strike with your staff against a different foe. Your multiple attack penalty applies to both of these attacks as normal.
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.
