Champion; In-game gameplay.
Evelynn's charm initial cast ignores spellshields, or at least Nocturne's.
Initial casts have never been unblockable. I see no reason for this one to suddenly be so.
Fighting Evelynn in Ascension.
Cast spellshield, then have Evelynn start her charm ability.
Player Note: I also noticed Eve's W doesn't show as a debuff on the buff bar. Made it harder to tell, but from the replay we can see clearly from not only audio clues but animations, Eve clearly turns to cast W after we see Nocturne's spellshield up, which blocks spells immediately.
