Your mastery of the shield and weapon bond has made you an expert in using shields, as a result, you are able to use your shield as a thrown weapon with the ricochet property. If the shield you wield requires attunement you can add 10ft to the weapons thrown range and increase the damage by an additional d6. Additionally, donning your bonded shield no longer requires an action.
Ricochet Property: To use this property a player must declare they are attempting to ricochet their shield to hit multiple targets before an Athletics check is made. The player can ricochet their shield off a creature or surface equal to the number of attacks they have per action as long as the creature(s) or surface(s) can be seen and is within weapon range. The initial attack must be successful for a player to ricochet their shield off of an opposing creature/surface and hit another creature/surface. If the attack is not successful and you declared the ricochet action your attack action ends and you must use your bonus action to recall your shield. For every “ricochet” your shield takes off a surface or creature after the initial throw, a -5 to hit is taken off of the original Athletics check as your shield loses its momentum (first ricochet off initial target -5, second ricochet -10, third ricochet -15, etcetera). Each successful ricochet hit requires a separate damage roll. On a critical hit, the initial creature/surface takes critical damage and any other creature or surface hit after will take normal weapon damage with NO -5 to hit. You can use your action surge to extend the ricochet barrage on a critical hit only.
Situational Ricochet: If a creature is within normal range, but cannot be seen around a corner, a player can attempt to ricochet their shield off a surface with disadvantage on the Athletics check and a -5 to hit on the roll after the initial ricochet. This action would use two attacks.
Range: 20/40ft (30/50ft if the shield is attuned)
Damage: 1d6 + your Eldritch Knight level. (2d6 + your Eldritch Knight level if the shield is attuned)
