If Elise uses q in human form, and then switches to spider form immediately, the duration of her Q extends to about 30 seconds rather than the standard 3. I am under the impression that QSS removes the the spell (hearsay not 100% sure).
Large problem is the amount of abusing and exploiting of this bug.
I've seen this reported a few times, but without proper formatting of the title (which i think i've done correctly) so hopefully this will help bring more attention to this.
Will be testing to see specifics in Customs.
EDIT: must change to spider form before q lands.
