In my earlier thread,
Undistractable, Single-Minded came up, as it was at least adjacent to the idea.
So that led me to wonder what Single-Minded would look like broken into its component pieces. There is one advantageous part, and two disadvantageous parts that are closely related. I've marked them with a '+' for adv and a '-' for disadv.
These are (quoted from
p. B85):
(1) + "You get +3 to success rolls for any lengthy mental task you concentrate on to the exclusion of other activities, if the GM feels such focus would be beneficial.
(2) - "You tend to ignore everything else while obsessed (roll vs. Will to avoid this),"
(3) - "and have -5 to all rolls to notice interruptions."
How would you price each of these out separately?
On a related note, does the +3 to success rolls from (1) apply to the Will-3 roll to
maintain Concentrate as well, or only to the success roll of the spell or skill or whatever that comes at the end of lengthy concentration?
