Dragon Claw
Basically, Dragon Claw is the strongest defensive equipment when facing squads with a lot of magic damage.
Furthermore, Dragon Claw does not provide any additional effects other than magic damage reduction.
Blood sword
The problem of Blood Sword is similar to Dragon Claw as this item only brings a single effect to the owner: blood drain.
Besides, with the appearance of the Blood Vapor system with the effect of providing recovery ability, Blood Sword is rarely used.
Tim Bang
This item has a fatal weakness: the range of impact is not large, so it can only reduce the attack speed of melee champions.
Another reason why Ice Heart is becoming increasingly `wasted` is the excessive popularity of the Grand Master system.
