• Gets the bonus once for each creature it blocks or is blocked by that meets the criteria. [D'Angelo 2001/08/31]
• If a creature enters a blocking situation with the Giant Shark due to being part of a banded group of attackers, the Shark will get the bonus if that creature is damaged at that time. [D'Angelo 1999/03/12]
• The bonus happens when a previously damaged creature becomes a blocker and the bonus is not removed if that creature is removed from the blocking situation by any means (such as being killed or by General Jarkeld). [D'Angelo 1999/03/12]
• Only gains its bonus if the blocking creature was damaged before blocking was declared. Damaging the creature later will not give the Shark the bonus. [Duelist Magazine #3, Page 7]
