WARING - (Boots Optional)
Now your wondering, Rageblade? But let me explain.
Black Cleaver- Most common item when slowly breaking down opponents. Its still useful even without champs without armor.
Titanic - Overall great item. Provides health and AoE Damage. Also comes with a great active which comes with alot of damage.
Rageblade - Rageblade is a underrated item for Kled. Its so useful because of the passive which helps with Frozen Mallet, and the stats with it. The 25% attack speed helps with regaining your mount while u kite auto attack. Especially with your W Passive, Rageblade and your W is what makes Kled feel unkillable. TL;DR Rageblade helps with kled when he's dismounted. With rageblade, gaining his mount is so much easier.
Frozen Mallet - Combos well with Kleds W, and Guinsoos Rageblade. Again, the extra health and damage makes Kled wayy to strong.
Boots - Situational
Deaths Dance - Cooldown Reduction helps with W and Q Spam, and the Passive helps with sustain in team fights. Very useful
