As for the Arrow if Time being an item, the only thing that I can come up with is Combo Upgrates from the flash game as an Active (Unlock by the item's upgrates) that you customize in the fountain and you select via cyclical selection (You press once and moves the current modifier to the next one in the rotation, rather than rotating by its own and reactivate to stop it like TF's W.)

What bothers me is that, under this system, how would fit the in-game selection panel for arrows? Because thus far 2 of the 3 controllable components are adapted (Favorite Combos and Fortress' Actives), and mixing them outside base seems obnoxious for how much time you could invest in it for the lack of safety and useful time you'll have.
