can you roll a dice for Eli to potentially see it, I dunno if he can see invisible objects tho, so allocate the bonuses he'd have, I'd say anything above 18 would be him seeing it without needing sight hax, going down to 15 if he just has enhanced eyesight, but if he has ability to see invisible objects I'd say anything above 5
DnD mechanic bleed, anyhow yeah, if he sees it coming Jolt is quite open to an attack right now
