@GM:
"I have discovered important information regarding these spider creatures. I would be willing to share it in exchange for that metal eye."
Is saying this allowed, or is it against the spirit of the game?
Sorry for the late response. You can totally try to bargain with people and such. Arguing over who gets what loot is part of every group dungeon crawler. That's how interesting opportunities and rivalries form.
Another example: You split off from the party to explore a narrow passage too small for ordinary humans to fit through (Puppets can squeeze through), and discover a cool sword artifact. You could definitely try to keep it hidden from the other group members under the justification that they'd want to sell it, whereas you want to use it.
That said, I'm not sure if the information you have is worth handing over that piece of tech
At this point it's a bit petty.
@DBZ: I meant to ask this earlier, but how does the eye grant a bonus to Reflex rolls pertaining to ranged weapon attacks when you mentioned before that guns use a set dice pool?
Good question. A ranged attack uses 3 + the weapon's Strength as a baseline roll (yours are Strength 5, by the way, since they're hefty weapons mounted on a robot), and then you roll your Reflex in a separate pool. The 3+Strength/Bonuses adds regular Hits, while the Reflex contributes 'Skill' Hits that only apply to the extra difficulty added by modifiers such as evasion, camouflague, and such.
When you attack something, the difficulty of hitting it is equal to an Armor Value, 1 by default. Being in motion adds +1 to the difficulty, but counts as being evasive. Reflex can only nullify the evasive modifiers, it can't contribute Hits toward the Armor Value.
For an example, say you have 3 Strength and 3 Reflex, and +1 to using your gun due to feats. You attack something with 2 Armor Value, and it happens to be some kind of crazed psycho-ninja with +1 to its evasiveness in addition to the base +1 for moving. It's coming at you.
You attack, rolling 6 dice for the main pool and 4 reflex+bonus dice. You score 1 normal hit and 3 Skill hits. The Skill hits nullify the +2 evasion modifier, but since you didn't roll enough in the main pool to surpass the Armor Value, your shot glances off. (but since you hit the target you might hit an exposed trinket or piece of gear)
If you had rolled 3 Hits + 0 Skill, the difficulty of hitting the target is 4, and so your attack would miss.
