In the campaign I am in my character's father was a Warden who is in a coma while his disembodied spirit haunts his Sword. Which my character now wields. My character has an appropriate Aspect which is primarily how we have been handling it. His father is constantly riding him about this or that which is distracting and a pain in the ass at times (imagine your very strict father floating over your shoulder). So we have quite a few Compelling situations and his years as a Warden can be Invoked as well. However, we did stat him up by trading his Evocation and Refinement for Spirit Form and Physical Immunity:
JOHN FRANCIS YOUNGBLOOD II
TEMPLATE: SPECIAL
HIGH CONCEPT: MOSTLY DEAD WARDEN HERO
TROUBLE: MY SPIRIT IS TRAPPED IN MY SWORD, MY BODY IN THE HOSPITAL
ASPECTS
I MAY NOT BE A GREAT DAD, BUT I LOVE MY KIDS
DID I FORGET TO TELL YOU…
SKILLS (+39)
SUPERB +5: Presence, Contacts
GREAT +4: Discipline, Lore
GOOD +3: Conviction, Rapport, Weapons
FAIR +2: Athletics, Burglary, Stealth, Scholarship
AVERAGE +1: Deceit, Investigation, intimidate, Alertness
POWERS (-11)
SPIRIT FORM [-3]
PHYSICAL IMMUNITY [–8] (+3 Spirit Magic and Exorcism)
THAUMATURGY [–3]
TOTAL REFRESH COST: 11
He would likely have quite a few points left over given his level of skill but we had ruled that he could only do Thaumaturgy given his situation.
After reading GS we would likely have to reevaluate that.
