How hard is Xerath?

He is all skill shots, but all of his skill shots have pretty generous hit boxes.

His entire kit are skillshots. It comes down to how good you are at predicting the enemies movements and how good you can aim skills.

I'd say xerath is a 7/10

Three of four skills ignore minion block and generally outrange their competition; two of four are CC, and his ult allows him to influence fights he's not even taken part in.

Immobile doesn't mean he's hard to play; it means he's easy to catch out. Even still, he has a stun and a slow on separate skills. He could tie off an escape provided he isn't getting 100-0'd (which doesn't happen as often as League players like to play up). He also gets some easy mana sustain off his passive which is nice.

Xerath just has to land his skills and doesn't really have to work super hard to do that. I'd say he's pretty easy. Comparing that to someone like Lux, who already now has to factor in weaving her passive (or losing out on potential damage).

Fairly hard, if you don't put yourself at risk during laning phase to proc your passive you are going to have mana issues.

His skills aren't so easy to land, all have delays and require also some decision making. Easy to push the lane.

Positioning and skill shots.

i wouldn't say he's necessarily hard to use but most of the time if you do somewhat decent people say you are scripting because xerath is like the test champ for scripts from what i seen
