Do activated/triggered abilities from permanents still resolve if the permanent is killed before the ability resolves on the chain?

Ruling: Once a triggered or activated ability has been put on the chain, it resolves regardless of whether its source permanent is still alive.

Nuances:

• If the ability references characteristics of its source (e.g., "deal damage equal to my might"), the ability still resolves but won't do anything because the unit is no longer there and its characteristics can't be referenced.
