Fighter / Assassin item idea.
Bladed Buckler (melee only) 35 AD 45 Armor
Build:
+
+ 550GP
Total: 2150GP
Unique Passive Bladed Counter: After being hit by an enemy basic attack next basic attack against that champion within 2 seconds is replaced by 30% attackers AD + 90% AD and inflicts Grievous Wounds for 3 seconds. This effect can only be triggered once every 3 seconds.
This is just a little idea I had while looking at Assassins and Fighters in the current meta. This would given them just a small mix of durability and offense so that they can get right in the face of the other team and do some work without one crit resetting the enemy HP bar and bursting them out. Its also cheep so you can build it while behind. The idea being that it will let you skirmish better in those moments when you catch someone out so you can start turning it around.
