As to the stuff you and @
Manbearcat have been discussing in the last few posts - I've only skimmed it, but you could use a Fear keyword on the "100 eyes" debuffs, and/or psychic damage, to help bridge the gap between mechanics, martial/supernatural, and player autonomy over the PCs.
That's actually a great idea but given that the trap conveys no damage, you would probably want to have the debuff afflict those that have been hit by the Will attack with Vulnerability 5 Psychic/Fear. This would allow an explicit bridge to the concrete implications of the "Paranoia" or "Fear" effects without afflicting them with a Condition and its accompanying Track. You could then use the buff portion to provide the Kobold Commandos with the Fear/Psychic keywords for their M/RBAs during the encounter.
This, of course, only works if you're wanting to go the route that Infyrana/"The Mountain" (as in the color's depiction) is performing reconnaissance at all times through The Weight of a Hundred Eyes (basically a scrying/enchantment trap) and infusing the Kobold Commandos with her knowledge and awful specter (the fear/psychic effects).
If you want the strategic adaptation of the kobolds to be Infyrana-neutral then this would not be the route to go. The questions would then become:
- Who created the trap and, through that creation, how precisely does it function?
If the answer is "this particular kobold clan" or "all kobolds" then:
- How precisely does it work as a conduit for the kobolds strategic adaptation and through what means (divination, telepathy/prescience)?
- If it is mundane, rather than supernatural, how exactly is all of this pulled off?
If it is Infyrana-neutral, if it is mundane and therefore basically like a Halloween Haunted House, then you're probably best just giving the PCs some sort of Combat Advantage debuff and giving the Kobolds Commandos
n bonus to damage with Combat Advantage. However, just like in a well done Halloween Haunted House, the PCs may know that the the trap is not malignant with supernatural vigor...but a corner is still a foreboding omen of ill portent as something is likely to be popping out at you! Unfortunately, that still would still not give you any pervasive "paranoia" element which permeates beyond the encounter when the PCs have found a cozy location for an extended rest (which will pretty much always be unmarried geographically to The Weight of a Hundred Eyes). You need a mechanical effect to enforce it outside of the encounter. The PCs may be attacked by the Kobold Commandos during an extended rest, but how will they associate that with The Weight of a Hundred Eyes?
