After putting Hamel into one of my teams, I discovered the whale has an upper limit of 40 stacks. So long as you ACTIVELY heal the whale it counts as giving one stack, which means the faster you heal/regen the whale the faster you'll stack the debuff. You don't even need the whale at full health. Hamel is best for this, while Ariel is probably second best. Du Ruo heals too slowly even with both her ults cast around the whale.
