What about an assassin item for AP assassins?
Specifically AP Assassins aka fizz, diana, Akali ect. As an AP assassin or atleast as a standard AP assassin your entire kit is all in or no in with barely any middle ground. To do what you're meant to do you need to one shot a VIP champ or you will get counter bursted by another assassin, a mage, or destroyed by an ADC. The issue is that with shifting metas, the slowly decreasing average of AP in itemization, and MR and counter burst becoming more readily available to all sorts of champions, this goal is increasingly hard to get to.
MR Is fine for now and the meta is also at a decent state imo but the one thing that I really do wish I had more options to beat are flat shields and HP spikes. With AP itemization losing flat damage more and more as time goes on shields are becoming stronger and stronger against the AP assassin group of champions by the patch but they don't have any way to really counter it.
This is why I'm extremely excited for the new hextech as it'll be a perfect option to be used as a shield popper against hexdrinker but at the same time it won't be optimal and will indeed be really inefficient on certain champions who need that sort of flat damage which is why I really do think AP assassins could use something abit more directly tuned towards them.
Now alot of people will probably downvote me as this group of champions also include commonly hated champions like fizz but AP in general is in abit of slump and with the next patch nerfing flat damage even more making the champion group even weaker I think it would be nice if AP assassins also got abit of love like the mage rework is going to do for them but in the form of an item instead.
Now I know very well that Ludens Echo has something close to what I'm talking about but that's also not completely viable on every champion. Alot of AP assassins have to build utility and more defensively to compensate for the fact that they likely have to dive head first into the enemy to use their kit so fitting in an item that's all damage is not typically worth having to sacrifice an item slot.
Unfortunately I know that any concept I might spew out probably won't be all that balanced so I'll refrain from doing that but I still want to get the point across.
is strong but poorly designed and worthless in an ad match up
is garbage
is just an expensive boots and not an item and you usually need to take cdr from the boots. I don't think they need a specific item designed to then, separating ap assasins from mages is a lot harder than separate ad assasins from marksmans. What they need is a reliable flat mp source what helps them to counter effectively mr rush in the mid game.

which only gives 35 MR.
35
Your

in those last two slots and its a fucking wash.
Hell,
