Enchantment as High Crafting Skill

See Wild Criticals, GURPS Power-Ups 7: Wild Card skills, p. 26 for such an example.
Some GMs allow House Rules and/or perks to increase it in a similar way. I think -9 is a good cap though.

As for High Craft, I use High Craft Powers (p. 205), Enchantment Through Deeds and the section on Meditative Magic in GURPS Thaumatology to handle this in general with a few house rules to handle this.
200 hours studying can grant a character point and this is the core of the Meditative Magic section. So I figured it was fine to apply the same process to a High Craft skill. That is slow but Enchantment through Deeds and the named Possession perk can ad more later and I have some house rules (basically a mini-magic system) that I throw in the mix to speed things up a bit. For example using magical materials, based on Thaumatology and the Material magic article in Pyramid.
