I'm personally against Learning thru magic but if it is possible I would have it this way:

Guidelines:

CrMe

General: Learn a specific knowledge at normal speed (Base quality 4). Ritual.

- Add one magnetude to gain one point of quality

** Each Rank gained awards one warping point (minimum 1 & add one for partial)

Level 35 Gain 1 Rank of temporary knowledge to no more than Rank 3

Level 40 Gain 1 Rank of temporary knowledge to no more than Rank 5

Level 45 Gain 1 Rank of temporary knowledge to no more than Rank 7

Level 50 Gain 1 Rank of temporary knowledge to no more than Rank 9

Level 55 Gain 1 Rank of temporary knowledge to no more than Rank 10

- Rituals

** Each application of this spell Causes warping

Ex. The Truth about Hermectic Law CrMe Level 15 (Base, +1 Touch, +2 Ring, +0 Circle) Ritual

Each season spent within the Ring, the target gains insight & clearity of the mind that allows to lean the subtilities of the code. The target gains 4 xp per season spent. If the target has the virtue clear thinker, he gains 3 extra Xp per season and one warping point per rank gained or partial rank gained.

Angus had 5.0 in hermectic Law but has been accused of a high crime for the next tribunal. He need to find the answers he seeks. He spends 3 seasons within the ring contenplating the truth & gains 3x4 (12XP) + 3x2 (6 Exposure XP) for a total of 18XP. Not enough to gain a rank. Angus does gain 1 warping fro the knowledge gaine & 1 warping point for beeing under the effect of a countinuous spell for a total of two warping points & now has 5.18 in hermetic law.

Ex2. The Truth about Hermectic Law CrMe Level 55 (Base, +1 Touch, +2 Ring, +0 Circle, +8 greater quality) Ritual

Angus gains 12 XP per season + 2 exposure XP for a total of 14XP. Over the 3 seasons, Angus gains 42XP which bring him to 6.12. he gains 2 warping points for the knowledge & 1 more for the continuous effect for a total of 3 warping points.

Angus will need to roll for twilight avoidance somewhere throughout the Learning experience (SG's call) since he will be gaining 2 warping points due to the experience.

Ex3. The Truth about Hermectic Law CrMe Level 60 (Base 45, +0 Personnal, +3 Moon, +0 Ind) Ritual

Angus neededs to know how to save his ass ASAP. The tribunal is just 2 weeks away. He gains 1 temporary rank in Hermetic law & one Warping point.
