Broad Shield:
This is another one of those powers that creates a unique mechanic (in this case, the mechanic of choosing a "direction" to defend from) that is not fully explained.
Suppose we have the following scenario:
Code:
* 1 2 3 4
A . . . .
B . X . .
C . Y . .
D . Z . .
E . . . .
X, Y, and Z are PCs. Suppose Y is a martialist, and he chooses to defend from the right. Then if a monster is at C3 and attacks Y, then Y will get the bonus. Now is "left or right" relative to the direction chosen, so X and Z are included? If a monster attacks Y from B3, does Y get the bonus? What happens if there's a reach monster, and he attacks Y from B4? etc. etc. etc.
Immoveable Object:
Add the word "may" between "you" and "retaliate" in the Special line.
Also, the wording of the "Special" line seems to imply that "choosing to move" is something that you do when you get attacked, which does not seem to be the case. Maybe what you should do is move the "if you are attacked ... as described below" section to the Effect line.
Also, the wording of the Special line say you can retaliate when you are attacked, but the wording of the actual attack says it only triggers when you are hit. Which is it?
Dance Around my Foe:
The "3 + Dexterity modifier squares" is not necessary, as it is always possible to get from one side completely around to the other in that many squares (assuming your dex is at least +1).
Note that in your, power, if you were in the following position:
Code:
* * * *
* M X *
* X O *
* * * *
where M is the martialist and the X's and O's are enemies, if the player uses this ability targeting O he cannot get around because he is blocked by the two X's, even though there is free space around. Is this desired?
Understand the Enemy:
What does "engage in combat with any other enemies" mean? Does it mean attacking them? Being attacked by them? Being in melee range with them?
If you engage in combat with any other enemies, does the bonus go away? This effect seems confusing because it has an "until the end of the encounter" effect but also a "sustain" effect. The RAW interpretation (as I understand it) would be that if you stop being able to sustain it, then your bonus stops going up but you get to keep whatever bonus you have untilt he end of the encounter. Is this desired?
Also, can you increase the bonus indefinitely? If so it is VERY powerful. I would suggest something like +2 to start, +1 additional each round, maxing out at Wis mod or something like that. Even then it's pushing the high side of power.
