Hello, a friend of mine is trying to make a battle sorcerer using the Arcane Disciple feats to supplement their spell list. They've said that it adds to your spells known, but from what I understand it only adds to their list of potentially known spells.

Add the chosen domain's spells to your class list of arcane spells. If you have arcane spellcasting ability from more than one class, you must pick which arcane spellcasting ability this feat applies to. Once chosen, this decision cannot be changed for that feat. You may learn these spells as normal for your class; however, you use Wisdom (rather than the normal ability for your spellcasting) when determining the save DC for the spell. In addition, you must have a Wisdom score equal to 10 + the spell's level in order to prepare or cast a spell gained from this feat. Each day, you may prepare (or cast, if you cast spells without preparation) a maximum of one of these domains spells of each level.

If a noncleric enters a prestige class that allows access to a domain, the character still gains access to the domain. She can use the granted power bestowed by the domain normally. If she memorizes spells like a druid, paladin, or ranger, then she can simply choose to memorize one of that domain’s spells instead of one of her usual spells, but never more than one domain spell of each level. If she is a spellcaster who keeps a spellbook as a wizard does, then she must fi nd or purchase a scroll of that spell and pay the usual price to scribe the spell into her spellbook. In cases where the spell is only divine the wizard may scribe a divine scroll into his book. The wizard then may memorize one domain spell of each level each day. If the noncleric is a spontaneous caster like a sorcerer or favored soul, then she may select a domain spell to add to her spells known whenever she would have an option to choose a new known spell. A sorcerer does not get to exceed his normal limit of spells known. Once the domain spell is known, the sorcerer may cast it freely. Unless the prestige class specifies otherwise, such spells are considered arcane spells when cast by arcane spellcasters.
Seems clear cut to me, but I wanted to know your opinions on it as I am not experienced with sorcerers.
