Count the number of lore counters on Scroll of the Masters as the activated ability resolves to determine how big a bonus the target creature gets. If Scroll of the Masters isn't on the battlefield at that time, use the number of lore counters on it when it left the battlefield.
(11/24/2014)
Once the activated ability has resolved, changing the number of lore counters on Scroll of the Masters won't affect the bonus that activation granted.
