关于这个合成毒液里毒药的等级，比如这个，2级—黑蛇毒，原质苔，条纹毒蕈，是指我职业等级到达2级才能准备，还是职业能够准备2环公式后才能准备呢，还请大佬们解答
原文如下：
合成毒液（Synthetic Venom，Ex）：合成毒液 当编毒师准备化合炼成时，她可以使用化合槽位准备短活性的毒素而非化合。一下毒素可以被准备进化合槽内。
1级—砒霜，巨型黄蜂毒，中型蜘蛛毒，
2级—黑蛇毒，原质苔，条纹毒蕈
3级—青嘶泣，巫妖之尘，幻夜余烬
4级—暗掠者粉末，紫虫毒，三眼毒（third eye，暂译）UW
5级—死刃夜露，毒芹汁，猎巫人之剑（witch hunter’s sword，暂译）UW
6级—黑莲汁，龙胆汁，君王沉眠
通过GM同意，可以将其他毒药加入此列表中。
这些毒药的强韧豁免等于10+编毒师的智力调整值+毒素的化合等级。以这种方式创造的毒素是不稳定的，如果不使用，一天后就会失效。一旦毒素被使用于目标，其持续时间等同于正常毒素，即使超过1天。除非编毒师有灌注炼金发现，否则这些毒素只能被施加于编毒师的武器（如果是这么用的）上。
Poison Lore (Ex): A toxin codexer gains the poison lore ability at 1st level. This ability is otherwise identical to the investigator’s poison lore class feature.
Synthetic Venom (Ex): When a toxin codexer prepares his extracts, he can use his slots to prepare short-lived poisons instead of extracts. The following poisons can be prepared into extract slots:
1st—arsenic, giant wasp poison, medium spider venom;
2nd—black adder venom, id moss, striped toadstool;
3rd—blue whinnis, lich dust, sassone leaf residue;
4th—dark reaver powder, purple worm poison, third eyeUW;
5th—deathblade, hemlock, witch hunter’s swordUW;
6th—black lotus extract, dragon bile, king’s sleep.
Additional poison selections can be added to this list with GM approval.
The Fortitude save DC of these poisons is 10 + the toxin codexer’s Intelligence modifier + the extract level of the poison. Poisons created in this way are unstable and become inert after 1 day if not used. Once the poison is administered to a target, the duration is as normal for that poison’s type, even if longer than 1 day. These poisons can be applied to weapons (if applicable) only by the toxin codexer, unless he has the infusion alchemist discovery.
This modifies alchemy and replaces trapfinding and the investigator talent gained at 3rd level.
