Ecstasy (Su): Once per day per class level, a prophet of Erathaol can enter an ecstatic state, allowing a celestial to seize control of her mind and speech. This is sort of a lesser version of channeling celestials (as described in Chapter 2), in which the prophet simply becomes helpless for 1 round while a celestial speaks through her. What the celestial says (and who it is) is entirely up to the DM, though it is always at least tangentially relevant to whatever matter is at hand. As a rule of thumb, this ability can have one of the following effects:
* any Knowledge check (with a bonus equal to the prophet's character level +5)
* a bardic knowledge check (with a bonus equal to the prophet's character level +5)
* a divination spell
* a detect evil spell
* an enthrall (the prophet can continue speaking on her own after the 1 round of ecstasy, continuing the effect)
* a good hope spell
* an atonement spell
* like a phylactery of faithfulness, allowing the prophet to identify evil creatures and avoid evil acts
* if the prophet sacrifices 500 XP, a commune spellUnfortunately, at the instant a prophet of Erathaol cedes control of her mind and invites a celestial to take it, she is vulnerable to possession by less beneficent spirits. If a fiend or ghost capable of possession is in ethereal form, within 30 feet of the prophet, and not flat-footed when a prophet enters her ecstasy, the creature can attempt to possess her immediately. The prophet takes a -2 penalty on her Will save to resist the possession, and if she fails she is not aware of the creature's presence in her body. The creature prevents a celestial from entering, and might pretend to be the celestial, speaking as the prophet's companions expect. If the creature chooses not to make its presence known in this way, it seems as though the ecstasy simply fails.
Spells per Day/Spells Known: At 2nd level, and at each level thereafter, a prophet of Erathaol gains new spells per day (and spells known, if applicable) as if she had also gained a level in a spellcasting class she belonged to before adding the prestige class. She does not, however, gain any other benefit a character of that class would have gained (improved chance of turning or destroying undead, metamagic or item creation feats, and so on), except for an increased effective level of spellcasting. If a character had more than one spellcasting class before becoming a prophet of Erathaol, she must decide to which class she adds each prophet level for the purpose of determining spells per day.
