Spell-Like Ability: An archmage who selects this type of high arcana can use one of her arcane spell slots (other than a slot expended to learn this or any other type of high arcana) to permanently prepare one of her arcane spells as a spell-like ability that can be used twice per day. The archmage does not use any components when casting the spell, although a spell that costs XP to cast still does so and a spell with a costly material component instead costs her 10 times that amount in XP. This ability costs one 5th-level spell slot.
The spell-like ability normally uses a spell slot of the spell's level, although the archmage can choose to make a spell modified by a metamagic feat into a spell-like ability at the appropriate spell level.
The archmage may use an available higher-level spell slot in order to use the spell-like ability more often. Using a slot three levels higher than the chosen spell allows her to use the spell-like ability four times per day, and a slot six levels higher lets her use it six times per day.
If spell-like ability is selected more than one time as a high arcana choice, this ability can apply to the same spell chosen the first time (increasing the number of times per day it can be used) or to a different spell.
그냥 아크메이지가 문장이 나쁠 뿐이라고 보는데. 코어 상위직도 그런 잘못 쓴 부분 또 있음. 그러니 그 테이블 DM call이겠지 RAI로는 슬롯 하나 태워서 Sp 2/day 얻는 능력이고(고로 소서러 가능) RAW로는 영구적 프리페어 시키는 거라 위저드만 가능하겠고 RAI로 보더라도 저거 때문에 소서러가 프리페어 선결조건을 충족하진 못함
소서러 아크메이지 예제도 있는데 당연히 된다고 봄. 일부 상위직같은 경우 spellsknown 준다는 명시가 없는데 소서러 추천 상위직인 경우도 있는데 그거랑 똑같은 경우라고 보고
