Kardel is one of the easiest heroes to control in the game.But you can turn him into one
of the strongest heroes you have ever seen.Kardel is an AGI type hero so what he needs are
agility items.He has low life so he is considered "soft" so you need to make him
"harder".He is also ranged and has a slow attacked speed so he needs items to
increase attack speed and his over all speed.Here are the items that Kardel needs to
improve himself:
1.Quarter staff-he really needs this thing!
2.Boots of Speed-he is so damn slow!!!!!!!!!!
3.Boots of Travel-composed of Boots of speed-if you have enough money buy this thing so
that he can teleport himself.
4.Helm of Dominator-comprised of Mask of Death and Helm of Iron will-this will give him
life steal and the ability to control creeps
5.Butterfly-comprised of Eagle Horn,Quarter Staff(that's why you really need it),and the
Butterfly itself-if you want to,double this thing so that you have a 60% chance of dodging
attacks and it increases your hit points too. 
6.Power Treads-Keep clicking it to add up to your hit points or your life.
7.Bracer-composed of Gauntlets of Strength and circlet of nobilty-probably one of the most
important stuff that you need on Kardel.This thing gives Kardel the toughness that he
needs.
Well hope I helped you with Kardel !
