Cast
You call upon your muse to greatly increase the benefits you provide with your courageous anthem, rallying anthem, or song of strength composition. If your next action is to cast one of these compositions, attempt a performance check. The DC is usually the highest Will DC of the composition's targets, but the GM can assign a different DC based on the circumstances. The effect of your composition depends on the result of your check.

Success The status bonus from your composition increases to +2.

FocusFocus 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.
SpellshapeSpellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
