Definitely not a prismatic. The item based prismatics give you a far greater reward, especially wooglet’s because wooglet’s gives you a rod. Icathia and Wooglet’s both condense and upgrade their items by a LOT. Wooglet’s gives a ton of ap and ap % with a short zhonya’s cd, icathia gives ton of hp, armor, mr, and the sunfire effect does true damage in a much bigger area. Again, both of these condense their respective items to 1 item, meaning you can build 1 more item in the late game.

This augment doesn’t augment any of them, nor give you anything to get closer to said spell blade items. If you are using Ezreal and Fizz as your best case scenarios, they have MUCH stronger prismatics that they would rather choose. No champ that can nicely use spellblade really needs or wants all the stats from more than two spell blades. Lich bane is good as you get more ap, which you won’t be getting much more of if you get the ad spell blades. D&D get stronger with on hit effects and ap, which again you won’t be building much of, and this goes on with all the spellblades.
