Sylas Patch Notes are deceptive

https://na.leagueoflegends.com/en/news/game-updates/patch/patch-914-notes

"E shield granted on first cast; no longer blocks non-magic damage but blocks all magic damage for a duration"

E - Abscond "Now shields himself against all magic damage for 2 seconds on first cast"

Emphasis mine.

Now to me, "all magic damage" sounds like Sylas can't take magic damage for that short window. You know. All magic damage. That sounded awesome. It's thematic, it's unique and powerful, but definitely has weaknesses and can be played around.

But no. This is just a flimsy purple shield.

Now, they could have just put "magic damage", skipping the "all" bit, and it would have made perfect sense.

"Blocks magic damage for 2 seconds on cast"

That actually describes the ability. It blocks magic damage. Not all, but some.

Riot should really change the patch notes, or even consider actually implementing full magic damage immunity, for a shorter duration if needed. That would make it a lot more interesting. Being able to face-tank Final Spark or Primordial Burst with good timing would be tons of fun, and now that the cooldown is flat, there's a pretty long downtime.
