How to play as Karma
Keep moving sideways against Xerath's aimed spells and use Inspire(E) to blunt a hit or dodge the center of Eye of Destruction(W); Karma mains call a good Xerath a painful lane, so avoid standing still to trade. (Unverified: no source confirms this note.)
After Shocking Orb(E) misses, step forward and threaten Inner Flame(Q) or a Focused Resolve(W) tether before Xerath can reset his skillshot pressure. Do not force the approach while his stun is still available. (Unverified: no source confirms this note.)
Xerath's Eye of Destruction(W) slows and deals extra damage at its center, while Karma's Inspire(E) gives its target a shield and movement speed that helps them avoid the center and reposition against his follow-up.
