Called Shots

So a way for Boo to go for the eyes is a must but the standard rules are silent. So what to do? In my experience this can quickly get out of control if it is just a simple minus to hit. Every boss being blinded turn one for the rest of the combat by that plus ten to hit multi-attack ranger gets lame really fast. Beyond being on target it should also be a difficult usage of a specific ability to pull off a called shot. So how do we define this in game terms. In lieu of standard attack damage you may declare your intention to achieve an effect. For example, a player may declare they will attack the orc they snuck up behind but want to go for a crack to the back of the head to stun. The DM may either announce a DC and ability check to achieve the effect or declare the condition is not possible. The player will have to make a standard to hit roll and then make the successful ability check to achieve the effect instead of regular damage. If either the to hit roll or the ability check fails, the player has failed and the target suffers no damage or effect. After considering the DC and ability check required the player may choose to instead proceed with a standard attack. Examples of reasonable effects to declare are listed below.

• Blind with sand in the eyes (dexterity for right timing, lasts until end of the target's next turn)
• Stun with a head butt (strength to create enough force, lasts until end of the target's next turn)
• Knock prone with strike to leg (ability based on weapon used, note target will not be able to simply get up on the start of their next turn when done as called shot.)
• Disarm with strike to the hand (ability based on weapon used, knocking a target’s equipped item a desired distance and direction is reasonable to declare)
• Critical hit with a parkour leaping attack off wall (acrobatics, see house rule for critical hits)

So it really becomes a straight forward decision by the player to press their luck after being on target for an effect other than just regular abstract damage.
