Theurge (Su)

Benefit: The arcanist selects one domain or subdomain upon taking this exploit. The chosen domain must be one offered by a deity the arcanist worships. The arcanist gains that domain’s 1st-level power as though she were a 1st-level cleric. As a swift action, the arcanist can expend 1 point from her arcane reservoir to bolster her divine connection, allowing her to treat her arcanist level as her cleric level for the purpose of using this ability, which lasts for a number of rounds equal to her Charisma modifier (minimum 1). She does not gain any other abilities when using this exploit in this way, such as class skills, domain spells, domain slots, or domain powers gained at higher levels. If this ability is used to gain an arcane bond and a bonded item is selected, the arcanist can only use that item to cast spells of a level equal to the level of the spell that could be cast by her equivalent cleric level (limiting her to 1st-level spells unless she spends a point from her arcane reservoir). If the arcanist already has a domain (or gains one later), taking this exploit instead allows her arcanist levels to stack with the levels of the class that granted her access to the domain when determining the powers and abilities of her domain.
