Why Arcane Comet
Arcane Comet can really shine on poke champions who are able to proc the effect from a long distance. **TIP:** If you're only proccing Comet with Xerath's [Q] your hit rate is going to suffer. **Try using [W]s slow and [E]s stun to more effectively deal chip damage in lane**.
Why Manaflow Band
Manaflow Band is what makes Xerath Support possible. His [Q] and [W] mana costs are extremely high with without Manaflow you're going to struggle poking and harassing in lane. Try to use [Q] when the Manaflow effect is up so that you get the most out of the mana refund. **TIPS:** Always try to auto a minion when your passive is off of cooldown, to further sustain your poking pressure.
Why Absolute Focus
Absolute's bonus ability power is fantastic for asserting early game lane dominance from afar.
Why Scorch
Scorch is the bread-and-butter of Xerath support as it further** empowers your poking and oppressive damage in lane**.
WhyMagical Footwear
Magical Footwear is a valuable and safe rune option on nearly all champions (minus roaming supports), acting **effectively as a kill's worth of gold at 10mins**. The saved gold lets your opt into more AP damage items earlier than otherwise possible. If you're playing into a few scary assassins/divers (Zed/Nocturne) **Perfect Timing can be a great alternative for minimizing deaths**.
WhyCosmic Insight
More CDR means more spell casts/poke and thus more lane harass, playing up on your strengths.
The Brink of Infinity
Lane harassment and consistent damage output.

Why Arcane Comet
Comet's poking nature allows you to repeatedly proc Comet for additional harass damage. If **procced with [W] or [E] you're much more likely to Lane the Comet** thanks to the slow/stun.
Why Manaflow Band
Manaflow combined with Xerath's passive provides you massive mana sustain. **Xerath has massive mana costs on [Q] and [W] so make sure to use those abilities to get the refund**.
Why Transcendence
Transcendence allows Xerath to hit 30% CDR with Morello's alone for a massively powerful mid-game poke and harass. If you'd rather opt for **less, but more powerful spell casts, Absolute Focus is a great alternative**.
Why Scorch
Xerath excels at poking in lane and Scorch is the ultimate lane dominance rune. Combined with Comet, Scorch **should easily put your target in Coup De Grace range** very quickly.
WhyTriumph
Triumph is an all-around solid rune choice on any champion. The extra heal on kill/assists allows you to continue on in fights.
WhyCoup de Grace
Coup De Grace is the go-to rune for mid-lane mages who are looking to **pump out maximum damage** to back-line targets. Xerath's long range allows him to **hit the back-line** no matter where he is positioned, making him prime for taking full advantage of Coup De Grace.
