Ah. Okay. I actually didn't check when I was writing that, I didn't know that Jax's Empower would proc Muramana twice. That's.. interesting. That makes them "upon attack (projectile if ranged) connecting", then, since I know from testing that Statikk Shiv's lightning does not arc until damage is dealt from the basic attack (in Aeon of Storms, the equivalent item functions as soon as you get into the 'cannot cancel' part of your attack animation-- e.g. when projectile is launched, much like how Runaan's Hurricane launches the side-bolts when you launch your main attack.

Now that I think about it, Tiamat/Ravenous Hydra works the same way (going by videos of back when Tiamat splashed for ranged attacks).

Information is good, but Blind would, unlike Fiora, not let the charge be consumed if the on-hit does not go through (Jax's hits through blinds, iirc-- and I know that Vayne's  makes the following AA go through blinds). Precedent would be for a Physical Damage example of 'cannot consume buff unless the AA connects', I BELIEVE that Named_item_effect is the same as well. (i believe that only Nami's empowered strikes are consumed on attacks made while Blinded, in fact wtf why does it not apply the slow through Aegis Protection that doesn't even make sense within the context of the four different on-hit types that exist already which makes it either it's own category or makes it a hybrid between different ones-- the buff is consumed on-attack, but if the attack is negated then the effect doesn't apply at all..?! it applies cc though so shouldn't it hit through the negation of the attack except by Riposte?? goodness gracious what is this monster)

Framing is ridiculously hard. Proper framing == godliness, because it's so close to impossible if you don't plan quite far in advance. (Framing issues are probably the largest cause of misreading anything, if personal anecdotes are acceptable)

... damn it, I did it again. sorry.
