Would it possibly end up overpowered that her Soulbound can apply Rend stacks? I feel like this would promote some duo cases where an ally who could scale off of attack speed but also do well as support (i.e. Teemo and Kayle can both support decently and also both scale well off attack speed) would allow her to stack the ability twice as fast. If this is an issue you could make it so only one Rend stack per X seconds could be applied by the ally, the cooldown being per target (the on-target cooldown restriction would be similar to what Soul-Marked used to have for a similar issue, though that problem didn't stem from niche cases like this). This could be especially problematic seeing as the damage per spear was raised.
