Class Features
All of the following are class features of the Dracolyte.
Weapon and Armor Proficiency: A Dracolyte is proficient with whatever they were already proficient with.
Spellcasting: When a new dracolyte level is gained, the character gains new spells per day as if he had also gained a level in a divine spellcasting class he belonged to before he added the prestige class. He does not, however, gain any other benefit a character of that class would have gained (improved chance of controlling or rebuking undead, and so on). This essentially means that the character adds the level of dracolyte to the level of whatever divine spellcasting class the character has, then determines spells per day and caster level accordingly. If a character had more than one divine spellcasting class before he became a dracolyte, he must decide to which class he adds each level of dracolyte for the purpose of determining spells per day.
Prestige Domain Ex: At 1st level, a dracolyte gains access to a prestige domain based on his alignment. Good-aligned dracolytes (and neutral clerics who channel positive energy) gain access to the Glory prestige domain (and its granted power), while evil-aligned dracolytes (and neutral clerics who channel negative energy) gain access to the Domination prestige domain (and its granted power). Dracolytes who are neither good nor evil (and who don't channel positive or negative energy) can select either of these domains, but once made, the choice can never be altered. The spells associated with the prestige domain can be selected to fill any domain spell slots the dracolyte has available. If the prestige domain is the character's only domain, he gains the ability to cast a domain spell of each spell level to which he has access once per day, in addition to those spells he already casts. P
Alertness: At 3rd level, a dracolyte gains Alertness as a bonus feat.
Foster Dragon: At 5th level, a dracolyte is entrusted with the care of a wyrmling dragon. The kind of dragon is up to the DM, but the dragon's alignment should match the dracolyte's. The wyrmling dragon follows the dracolyte loyally, and will even accompany him on adventures (though it receives no XP and can't attain new levels). If the wyrmling dies, the dracolyte cannot gain any additional dracolyte levels until he receives an atonement spell from another dracolyte or a cleric who worships a draconic deity.
Immunities Ex: A 7th-level dracolyte gains immunity to magic sleep and paralysis effects.
Keen Senses Ex: At 9th level, a dracolyte gains darkvision out to 60 feet and low-light vision.
Summon Dragon Sp: A 10th-level dracolyte can, as a full-round action, summon a dragon once per day. This ability is similar to a summon monster spell, except that the dracolyte summons an adult dragon of the same kind as the wyrmling dragon entrusted to his care (see above). The summoned dragon remains for 10 rounds and follows the dracolyte's commands.
