Iv noticed quite a bit lately, allot of those who should anger Radu don't because they are just on the edge of his perception range. Which is actually really close, enough so that he should be able to note some blatant oddities. Or monstrous/misshapen bodies.
Would suggest his perception range be much further, though sadly that also ends up cheesing it a little when he isnt supposed to be able to see around corners or through thick trees. . . . But on the other hand then there is clear freakish forms standing near enough to see but he doesn't say a thing or try and roust them from the area.
If it were possible. . . . Maybe a uniquely drawn trigger instead. That can be shaped to better represent his sight lines and still keep it fair and realistic?
