It's time for the patch notes! 4.3 brings about some stuff including a new champ, but for those of you too lazy to look at the site, I might as well give a rundown of everything.
Champions
Corki's Phosphorous Bomb now has a 0.5 bonus AD ratio.
Gragas took a couple of hits; his Body Slam's AD ratio was reduced but it increases with rank, and his Explosive Cask had a slight drop in AP ratio as well.
Kassadin got a couple of nerfs, notably to the base damages of Null Sphere and Force Pulse. His Null Sphere's silence duration was lowered by half a second as well.
KhaZix's Evolved Enlarged claws deals less % missing health damage, and Leap's AD ratio was gutted; instead, Void Assault got a couple of buffs.
Ryze now has more Health, and Overload's range has been buffed.
Skarner got a couple of follow-up buffs. His Crystal Slash costs less mana, and his Fracture has a stronger slow.
Teemo's Noxious Trap no longer scales as well with AP.
Vel'Koz incoming!
Yasuo's Resolve (shield) has been nerfed.
Zac's blobs now have a greater interaction radius for picking up and stomping out.
Champions - Crowd Control
All instances of Fear have now been changed to Terrify. In other words, champs no longer run in random directions when under the effects of Terrify / Unspeakable Horror / Jack in the Box, but instead run away from the source with impaired movement.
Champions - Insignificant Stuff
The following champs have received minor little things, some bug fixes:
Kayle
Sejuani
Twisted Fate
Volibear
Items
Tear of the Goddess now has a new passive where it grants +1 maximum mana to its Mana Charge every 8 seconds.
Doran's Shield's Health and Health Regen have been nerfed.
Spirit Stone items had their Health / Mana vamp decreased, but area of effect damage no longer halves this effect.
Boots of Mobility cost 800 gold but now have 25 for a base movement speed buff.
Ruby Crystal and Sightstone had their cost reduced, but same with the health that they provided. However Ruby Sightstone had the opposite effect.
All "support" items received changes. Check the notes for more details.
Team Builder
“Some Team Builder assets are included in this patch in preparation for an eventual two-day live beta test,” said Pwyff.
I think that's it.
The support changes will be interesting...let's see how they play out. I've played Vel'Koz a bit on the PBE, people are probably going to cry OP but that's the nature of newly released champions. He is a really cool champ though.
