The Revised Mercurian Magic Virtue
MERCURIAN MAGIC
Major, Hermetic
Your magical lineage and traditions are from the Roman priests of Mercury, which predate the Order of Hermes, making you especially skilled with Ritual Magic and magic used in conjunction with others. In addition to your standard spell allocation, you also know Wizard's Communion at a level equal to the highest level of Ritual spell that you know, and should you invent or learn a Ritual spell of higher level, you automatically invent a Wizard's Communion spell of the same level, without needing to spend extra time. Record only the highest-level Wizard's Communion that you know (since a lower level offers no advantage). Your Mastery score in Wizard's Communion is maintained even as the spell's level increases.
You may write a Lab Text of a Wizard's Communion of a level up to the level you know it at as a Season's work. A lab text of Wizard's Communion is not created as part of inventing another ritual spell.
When casting a spell using Wizard's Communion, you may add your Mastery score (page 86) in the spell being cast and your Mastery score in Wizard's Communion to the effective level of the Wizard's Communion.
Finally, any Ritual spells which you cast have only half the usual vis requirement. If cast as part of a Wizard's Communion, the main caster needs to have this Virtue to gain this benefit. If all the participants in the Wizard's Communion have this Virtue, calculate the amount of Warping Points on a botch as if there was a single caster and divide them amongst the communion's participants in order of ascending Wizard's Communion level (randomly when tied). Any magus that gains 1 or less Warping Points as a result need not check for Twilight.
Your concentration in Ritual magic has a downside, however - you may only cast Spontaneous magic using the rules for Ceremonial Casting (page 83).
