Eaglesoul

When you cast this spell, you beseech a good-aligned outsider for their aid against evil. The outsider infuses a small portion of its own power into you, making you a powerful force for good. You gain a +2 morale bonus on all Perception checks made against evil creatures, a +2 bonus on Initiative checks, and detect evil as a constant spell-like ability.

In addition, once during the spell's duration you can call forth a surge of holy power when fighting an evil creature. Doing so is a swift action that shortens the spell's remaining duration so that its remaining hours of duration become rounds of duration. For the rest of this duration, the surge of power grants you the following benefits:

Although this surge of power can be activated against any evil opponent, this ability activates automatically as soon as you attack any evil outsider, regardless of whether you hit or not, and regardless of whether you actually recognize that the target is in fact an evil outsider. In such cases the activation is a free action.

Nongood spellcasters can cast this spell, but doing so causes them to be sickened (for spellcasters who are neither good nor evil) or staggered (for spellcasters who are evil) for the spell's duration.
