Whenever a troop takes damage, a percentage of that damage will be dealt back to the defense that dealt it.
Level 1: 6% returned (4% for splash towers)
Level 2: 8% returned (5% for splash towers)
Level 3: 10% returned (6% for splash towers)
Level 4: 12% returned (8% for splash towers)

How about it?
