Hemomancer's red harvest ability is essential for its combat cycle, and currently, technically, is pretty much perfectly tuned to do the job it's intended for. However, one pain point is mis-clicking and entirely wasting your cooldown because you targeted your summon or some such.
As a results, I would like to request that red harvest's cooldown is reset if red harvest has no effect, either because the target has no blood, or is a summoned or allied creature. This would still leave a mild punishment for the skill issue, in the wasted round of red harvesting to no effect, but would prevent us from having to eat the longer penalty cooldown because your flying knife or ally's spider darted into your mouse cursor right as you clicked.
