Panthon's 
Pasive will block both Kalista's
Q and E (Perice and Rend), As stated Panthon's pasive will "block the next Auto attack and turret attack" but Kalista's Q and E are both "spell's" and should not be blocked by his pasive
MrPerson104 votesThey're spells which are added to her AAs. Quit bitching about the most OP and currently most mobile ADC with ridiculousness having a small bit of counterplay. she needs something to shut her ass down.

Why so salty man, I was just bringing up a flaw or something they need to adress becasue it shouldn't be like that because Panthon's pasive says that it only blocks AA's and Tower shots not spells. and to add to you saying that she needs counter plays just go play Leona or anyone with a stun that will shut her down
MrPerson103 votesCurrently, build AS and you can move faster than a full build level 18 Udyr simply with your passive. That's why Riot's nerfing her AS ratio.
You can't shut her down if you can't hit her.
Chinmoku no yoru2 votesYes, my Build gets a 2.50 attack rate my problem is the Pantheon pasive not being correct or a bug they overlooked
P.S. my build is 
MrPerson102 votesYeah, the problem with Kalista is how well she goes with AS stacking (from her passive jump) It's working as intended last I checked.
Tried recreating it, couldn't get it to block Q - however it does block the first E, as is intended as it's a buff to her AAs rather than a spell cast itself. I can try recreating the Q again, however I'm nearly 100% certain it didn't get blocked.
Chinmoku no yoru1 votesI reseved my information form a freind, posably they where doing too low damage but the E shouldn't be blocked because it's not and augment to basic like Wu Kong's Q or even Garen's Q so I don't undersatnad why it would.
P.S. they allready nerfed her so nerfing her agian will cause problems, atleast if they nerf her attack speed ratio the should bring back her E's % per spear to eaven things out
MrPerson101 votesIn what world is the most mobile champion being ranged with zero consequence to her mobility balanced?
Kalista's E: "*attacks impale their targets with spears. Activate to rip the spears out, slowing and dealing escalating damage."
It's an augment to her basics, not an individual spell cast
Chinmoku no yoru1 votesNot quite it's more like Zed's Ult that deals damage in addition to what he damages, it requiers her to AA just like Zed's Ult but in Zed's case he can also use abiltiys
MrPerson101 votesVery different scenarios. Zed's ult takes the raw damage dealt within the 3 seconds of his ult timer from all of his sources and deals a % amount of the damage on detonation of the mark.
This, however, is not the case. Her E is cast WITH her AAs. If you only land one spear, you only get to detonate one spear. If he happens to have block up for your detonation, it's blocked because it's still working off of your AAs as opposed to being a true spell cast which has nothing to do with AAs.
Chinmoku no yoru1 votesNot at all it's varry similar the only diffrence is that the damage isn't caped by a time limit unless you stop attacking, you also have to rember the diffrence between an augmented auto attack.

In refrance to your comment about Kalista's E "Attacks impale their targets with spears(pasive). Activate to rip out the spears, slowing and dealing escalating damage(activate said pasive)." if anything Pahthon's pasive should only block the applection of an extra spear
MrPerson102 votesProblem with her right now is how well she scales with AS, she's essentially a kiting machine - hence the incoming nerf on that.
Reporting in after a recreation attempt:
As pantheon, built up to block to 3 with AAs on minions then the following: e proc from Kalista hit, AA on kalista, blocked second E proc, W kalista, blocked third E proc - so it blocks E, as I believe was intended since it's a buffer to her AAs.
However I could not recreate the Q block after attempting 3 times.
