[Enhanced Sense] 360 Targeting with Discriminatory Smell

[mlangsdorf]

I reread Powers: Enhanced Senses, and I have no idea how to cost this effect:

I want a werewolf that can use his super-keen sense of smell to allow him to defend against hand-to-hand attacks coming from outside his field of vision.

Discriminatory Smell is a short-ranged, discriminatory sense (Enhanced Sense p 6). It can be used a as replacement for vision (Enhanced Sense p 6), but I can't figure out it's arc nor how I would increase the arc.

Can anyone explain how to fairly cost the effect I want?

Sounds like the "360 degree Vision" Advantage, with minor Limitations.

1. No penalty to defend attacks from side or rear.
2. Can Attack to sides and rear at -2.
3. +5 to detect Shadowing.
4. Never surprised by attacks from behind, unless they are concealed.

So effect 1, 2 as stated. 3 could be limited to "scent range" whatever that is. 4. could be limited to melee attacks only.

I think something like -10% for [22] and you have what you need.

It has the effects of 360 Degree Vision, but only for things that have scent and with scent's usual short range acuity drop-off of 1/hex instead of visions drop-off based on SSR table.

But maybe simply using 360 Degree Vision as a base is the fairest way to go.
