Well, you'd do something like this:
Skills:
Fantastic: Discipline, Lore,
Superb: Conviction,
Other skills based on character concept as a whole
Powers:
Refinements [-6]
Evocation [–3]
Thaumaturgy [–3]
The Sight [–1]
Soulgaze [+0]
Wizard’s Constitution [+0]
Lawbreaker (Sixth) [–2]
A Few Seconds Ahead [-2]
Total: -17 Refresh
Specializations:
Evocation: Elements (Air, Water, Spirit); Power (Spirit +3, Water +1), Control (Spirit +2)
Thaumaturgy: Complexity (Chronomancy +2); Crafting (Strength +1)
Focus Items:
Staff of Time [+2 Offensive Spirit Control, +4 Offensive Spirit Power]
Enchanted Items:
Temporal Desynchronizer (10 shift Block or Armor 5, 5 times per session) [6 Enchanted Item Slots]
Rotes:
I Saw This Coming (12 shift Maneuver placing three Sticky Aspects on yourself, requires Staff and Lawbreaker.)
Chronal Flux (Weapon: 10 attack against everyone in one Zone, ages victims rapidly, possibly destroying them. Requires Lawbreaker and the Staff.)
Just Not There (8 Shift Block or Armor 4, lasting 3 exchanges, costs a 3 Stress hit. Requires Lawbreaker.)
Other Rotes will do other, similarly chronal things.
All this obviously assumes a combat Chronomancer, a Ritual Magician version would be somewhat different.
