Level 17-25 Stats
Take burrow strike at level 1 as it can help u escape and stun.sandstorm is to max because for each level u add the cooldown decrease by 10 second.I prefer adding stats since sand king is a ganging hero he does not need the farm.If the enemy has pushing hero like broodmother, adding caustic finale might not be a bad choice
Starting itemsThis is the best starting item imo.Just try to last hit to a bottle as soon as possible and rune control. U basically win the lane easily if u can rune control. Try to kill the enemy hero when u reach level 6 then procced to gang.
Urn Start
