take balohan or zenna with you to the Light mini base.
(do not kill the tower!)let balohan or zenna attack the creep first. after they
attack, use Dark Sprint on the creeps and get lots of EXP and gold but do not
loot thief rocks as they need it for thier tanking equipments.after u have lvl up till
lvl 6. do this at the enemy.
1.Dark Sprint
2.use War Boots to slow down or your "claming" thingy skill.
3.normal attack(if its hard to attack a hero, use Unholy Ground)
4.use Dark Sprint again
keep doing this untill the hero died.
