I actually came up with a template that matches your character perfectly on another thread. Btw i allow characters who take this template to take more than one refinement if they wish, but doing so they can never take Evocation. So its a choice either learn Evocation some day by advancing to a Sorcerer or Wizard or focus completely on Thaumaturaphy and become a more powerful Hedge Witch or Hedge Wizard.
I created this template because I felt there was something missing in the low level spell casters Templates. I felt that while the Focused Practitioner is well and good for some low level practitioners, it neglected to show those who have more well rounded mystical portfolio, but lack the ability to use evocation or Channeling.
Hedge Witches and Hedge Wizards are quite skilled at numerous spells and areas of magic, but they take time to actually cast their spells. This is reflected in their ability to use Thaumaturgy just like Wizards or Sorcerers but they lack the power or skill to actually wield Evocations.
Many Hedge Witches and Hedge Wizards colour their magic and spells with some alternative religious feel, being that many are also Wiccans, New Age believers, practitioners of religions like Sanitaria or Voodoo etc. This means that for them to cast their spells they need the trappings of their faith and their beliefs, for example most Wiccans have an altar which they practice their magic, including statues of various deities and other magical trappings like a pentacle, Athame, incense etc.
Musts: A Hedge Witch or Hedge Wizard must take a High Concept that declares his or her nature as a Hedge Witch or Hedge Wizard, such as MEMBER OF THE ORDO LEBES or SOCCER MUM/WITCH. In addition the Character must take the following supernatural power:
Thaumaturgy [–3] (YS page 181)
See the power description for more details.
Options: Hedge Witches/Wizards may take the Sight (-1) which would function the same as for Wizards and Sorcerers, but this is rare. In addition, they may take Refinement (-1), once per play. It should be noted that they can never take Evocation, if they want to purchase Evocation they must upgrade to Wizard or Sorcerer.
Important Skills: Conviction (YS page 124), Discipline (YS page 127), Lore (YS page 134).
Minimum Refresh Cost: -3
From the Casefiles: Kim Delaney (OW130). Also Anna Ash, (OW103), simply replaces Rituals with Thaumaturgy and raises her refresh to -3. In addition Charity Carpenter when she was younger was a Hedge Witch.
