There's only one process mentioned in the revised version.
Here's a rearrangement to make that clearer. Does it work?
Verditius magi are initiated into the Outer Mystery of Verditius Magic, which allows them to incorporate craft abilities into their magic. To do this, the magus crafts the item from raw materials as part of the first season of enchanting it. For a talisman or standard invested device, this is the season in which it is opened for enchantment. For lesser enchanted items and charged items, this is the whole process. If crafting the item would normally take the magus a season or less, this does not increase the time required for the enchantment. If crafting the item would normally take more than a season, the process takes a whole number of seasons that is at least as long as the time it would normally take the magus to craft the item. For example, if it would normally take the magus four months to craft the item, then it takes him two seasons to craft and enchant it. No matter how long this takes, it only includes the first season of enchantment.
As part of this process, the magus may add details that enhance the Shape and Material bonus of the item. These details give an additional bonus to all the item's existing Shape and Material bonuses equal to the creating magus's Philosophiae score, for the purposes of enchantment. These bonuses apply in the season that the details are added, as well as in the future. Other uses of Shape and Material bonuses, such as the casting bonuses from a talisman, use the standard bonus. Other magi refer to these details as Verditius Runes, but they are far more complex than that suggests, and do not normally look like actual runes. The total bonus from Shape and Material and Verditius Runes is still limited by the magus's Magic Theory score. Other magi get this bonus if they instill appropriate powers into an item created by a Verditius.
The magus uses the magic of the enchantment to shape the item. This does not require any Craft Ability, although most Verditius magi will use an Ability that they have, and the final form may be impossible to make by mundane means. For example, a Verditius magus could set a gem in a wooden lattice so that the gem cannot be removed without breaking the wood, without having any breaks in the wood to get it in. The final form must be able to sustain itself by mundane means once created; in particular, it must be strong enough to bear its own weight. If an Ability score is needed, use the magus's Finesse in place of Craft.
However, most Verditius do use mundane craft as part of this process. This is because a magus who does so may add his score in the relevant Craft Ability to all Lab Totals for enchanting that item, both in the first season and in the future. Thanks to his mystical link to the item, this bonus is always his current Craft Ability, even if it has improved since he crafted the item. Note that only one Craft Ability can be added to the Lab Total in a given season, even if the magus has more than one applicable to the item. The applicable Ability may, however, change over time — the magus should add his highest applicable Craft Ability. Other magi adding enchantments to an invested device do not get this bonus, even if they have the same Craft Ability as the creating magus, and even if they are members of House Verditius.
If the magus creates the enchanted item in this way, the number of pawns of vis needed to open the enchantment is reduced by the magus's Craft score, to a minimum of one pawn. The magus, or any other magus, may invest effects in the device as if he had paid the full, normal cost to open it.
A Verditius naturally reinforces Verditius Runes as part of the enchantment process, even when working on an item that has already been enchanted, and so if a Verditius working on an enchanted item has a higher Philosophiae score than the earlier Verditius enchanters, the Verditius Rune bonus increases. This also applies if a magus increases his Philosophiae score between seasons of enchantment.
