Although devotion to a single god enables some individuals to gain additional power, overriding
Weapon Proficiency: You gain proficiency with all the favored weapons of the deities of the Sovereign Host—the battleaxe, halberd, heavy mace, longsword, morningstar, quarterstaff, sickle, spear, and warhammer.
Spellcasting: At each level other than 1st and 6th, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in a divine spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one divine spellcasting class before becoming a sovereign speaker, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.
Bonus Domain: For every level you take in this class, you gain a bonus domain offered by one of the deities of the Sovereign Host. You cannot choose more than two domains offered by the same deity (for example, if you already have the Strength and War domains, you can't choose Good, since Dol Dorn offers all three). You also can't choose an alignment domain if your own alignment does not match it.
You gain the granted power of the chosen domain. If you have domain spell slots (as a cleric), you can prepare spells of the chosen domain in those slots as normal. If you instead add domain spells to your existing spell list (as an adept does), simply add the spells of the chosen domain to the appropriate class spell list.
Extra Domain Slot: At 3rd, 6th, and 9th level, you gain an extra domain spell slot, which can be filled by any domain spell of that level or lower. At 3rd level, you gain an extra 3rd-level domain spell slot. At 6th level, you gain an extra 5th-level domain spell slot. At 9th level, you gain an extra 7th-level domain spell slot.
