Dark Seal tacking- RIto? Why is this a thing.

did u mean stacking?

Because the 25% extra healing from potions isn't a unique passive. The other passive, the stacking ap one, is the one that doesn't increase the more dark seals you buy. The latter supposedly should be the incentive not to buy more than one, but it's being outweighted by the first. There's also the lesser gold loss. If you buy a Doran's, any of them, they sell for 40% of their original value as dark seals sell for 70% their base price. s on , for example, are 352% gold eficient. Most items are around 100% - 120%.
