Peewrath, the lightning dude.
Xerath is unique to this game; He requires specific and strategic positioning to actual deal damage to people. His Manual snare was really weird, he's relatively short range unless he uses it, but it roots him in place while he casts his abilities, his passive is practically useless, unless used against AD mids (and even then, it's pretty weak), his Q is godlike, and his Arcane Barrage is insane in teamfights. Xerath truly was a skill champion, who required players to think their actions through before they do them, and not think about what they're doing as they go along (I'm looking at you, Riven).
Anne den, REWARK. Nao he's gut new abilities on the PBE, and I suppose this is my "review" of sorts.
Overwhaleming power: Xerath gets mana from autos Every 12 secs, making him vulnerable to counterplay, AND forcing him to get into auto range to keep himself from going OOM, and Xerath likes poking from a distance.. Lame
Arcanopulse: Exacly like the old Q, but it charges like Varus's Q, thus slowing you while it charges. Does moar damage for longer charge, yatta yatta. Pretty good skill, not much change here. He's just slowed instead of stopped. Max 1st pls.
Old ulti, but it's your W now: Xerath uses his ult, but PLOT TWIST it's his W, dealing some heavy magic damage and slowing people in the center. It deals SUPER MEGA BONUS DAMAGE to people in the center, which is kinda like a Peona twist, and overal its probably his 2nd main burst spell. I'd max second.
Ball that's so shiny, it stuns people: Pretty much Mage Chains, except it's a skillshot, meaning he can't do anything to anyone unless they're out in the open. This hurts his combo more than Yi reks squishies.
Arcane Barrage combined with Locus of Power on mega steroids: Xerath is snared for a sec, then gets a massive range, and when I say massive, I mean rank 3 Caitlyn ult massive. Then, he gets to shoot 3 tiny fiurbawlz at people that deal PEANUT DAMAGE. The radius for every bawl is tiny, the damage is tiny, the range is massive, it totally interrupts your combo because you can't do anything while you're Ascended. Rito plz
I'll tale u wut: New Pearith is weird. His E>Q>W combo is the same as his W> E> Q> R> R> R combo, but his new ult doesn't fit anywhere in said combo; It's kinda like a long range snipe execute thing. I'm not saying the new Xerath is bad, it's just gonna take some time to get used to.
