"The Drain Value is the Force specified by the focus formula, plus 2 for each hit (not net hits) rolled against you in the Enchanting + Magic test in Step 5; since the Force cannot be higher than your Magic rating, the drain does Stun damage. If you’re still conscious after resisting drain, you can spend an amount of Karma equal to the actual Force of the focus to seal the deal and finish the focus. If you fall unconscious or don’t want to keep the result, skip the Karma expenditure and start over (probably after you’ve healed)."
So this is the result?
Drain = Formula's Force + 2 x roll (Formula's Force + Object's Resistance)
If so, this value can be higher than Magic...
