Hello,
i wonder if there is a bug or some change in d2r about casting sorcery because sometimes my sorceress fail to cast frozen orb, i mean, the casting animation is working but nothing … very annoying… is it normal ? a bug ?
Try to find some info with google but nothing, is anyone did notice that before ?
Thanks for you reply
I imagine online? The only thing I can assume is a connection issue, since there is client + server, bad connections will create lots of fake casting/rubberbanding… Try with offline if you are able to use hero editor real quickly to get a level 30 sorc. Is it better? If so might be a ping/packet loss issue… type /fps in game and report your ping. If high, may want to give some packet loss tester…
Actually this was in offline game 
i will try later to see if it’s happening again…
Were monsters hitting you when you casted?
How old is your potato?
Nope, for info i know the game very well, i’ve been playing d2 many years when the game was released, just buy d2r to redo the game with enhanced graphics…
i presume this was latency issue, because it didn’t happen in my last game session…
i will update this thread if it happen again.
Thanks for your replies
But if you were truly offline then there wouldn’t be any latency problems, only stutters if your potato sucks balls…so hopefull you truly meant offline versus playing by yourself online (which isn’t "offline) because the latter will result in these things if you have a trash connection.
Sorry, i’m french and i don’t understand what do you mean by “potato” in this context, yes my character is offline and my connexion is actually quite good.
i will try to find how to do the /fps and send my ping below…
And it just happen me twice, didn’t get hit by a monster…
When it’s happening i clearly see the sorceress doing the cast animation (with her arms) and also the little “twister” effect of casting the frozn orb around the character (sorry my english is maybe not so good to explain this proiperly) but no Orb 
It’s very frustating, im gonna look again on the net if i can find anyone who get the same behavior
Edit: /fps = latence = 0 as expected
Edit 2: i wonder if there is some relation with the fact i’m using a lot the Shift Key (woch i always do to stop the sorceress runing for casting my orb)
Edit 3: “only stutters if your potato sucks balls…” >> if i understand correctly “only lags if my graphic card suck” am i correct ? (Gtx 1080)
Does is not cast the orb or do you do damage but the orb is not visual? When i tried mosaic when it was first released i couldn’t see the phoenix strike spells even though it did damage. I love MA so had to try the new toy but quickly found out it was not for me.
i don’t think it is the Orb visual issue, because i just did some Test, go in a corner room, no monster around (so impossible i get hit), holding shift and casting frozen Orb , and it happen quite a lot actually, on thing i ve notice, when it’s happening i can see the fcr is quicker than a normal fcr between 2 orbs, i will try to record this.
Ok, thankfully OBS was still installed on my computer, here is a video of what happen, it’s a 22 sec video, it is happening at 16s
/easyupload.io/9m4la0
For info i’m casting in continue
Edit2: you have to add h t t p s : / before the /easyupload
Edit 3: i found there was some strange issue by the past that could have related behavior
-Quick Cast
Fixed an issue where key mappings with modifier keys (e.g. Shift/Ctrl/Alt plus another key) could get stuck in the active state. This was especially noticeable with Quick Cast skills.
Fixed an issue where clicking the left or right mouse button while holding a Quick Cast skill hotkey could cast the wrong skill.
So maybe what’s happening is something like this, where this is not orb that it is casting but the chill armor (wich have exactly the same cast animation)
Edit 4: did some other test, doing same protocole wihtout lauching the chill armor before, and once the “bug” happen nothing more seems to happen (not casting anything) … i’m so confused this is so annoying behavior
Edit 5: very strange , i thougt i get it by changing my gear and affecting the FCR, and then no issue anymore… very very strange , done testing for now, go back to kill some monster
