Officiele rulings

The cost to avoid the penalty must be paid when the ability resolves. You can’t wait until later to do so.

Paying the Heroism cost to allow a creature to deal damage does not prevent other effects from preventing it from dealing damage. Paying the cost only prevents the Heroism effect.
