Best Keystone for Xerath?

I am hoping that they add another line of keystone's and masteries to broaden the diversity

I think Stormraiders might be very good

I kind of like Stormraider's Surge on some of the immobile burst mages. It's neat for re-positioning a lot during teamfights or escaping a gank.

Well I would recommend you Thunderlords, but if you wanna go fancy just use Warlords Bloodlust... I mean there aren't many options, I know, it is sad.

Thunderlords: Burst and benefits Xer a lot because he must use a lot of magic pen in items and runes. DFT: Use it if you want to poke down your enemy, specially if you build Stormraider's: It can be quite useful, but it won't add any damage to your combo, or ratios (this mastery should be buffed).

Best one I've found is just thunderlord's for trying to clutch burst when being initiated upon.

There's really no viable keystone for champions with frontloaded damage like Xerath and Ziggs since they rarely hit 3 times to proc thunderlord's and deathfire sucks ass with aoe poke.

Really hoping there's gonna be some rebalancing or a new one for those.

Take Stormraiders.

Running around with the MS is hilarious
