Relatively new to DnD/TTRPGs. Playing a Barb with +0 to INT and -1 to WIS. I just realized that my party might be walking right into a gelatinous cube. What is considered "average" intelligence and wisdom? Would my character be able to reason through subtle clues that we might be wandering through a cube's lair?
The context is: Our party is visiting the same incomplete dungeon for the third time. DM has explicitly stated to us through a DMNPC of very high experience that the Kobolds in the dungeon repopulate so quickly that clearing the Kobolds on the upper floors is a common activity for practicing adventurers.
The clues are:
We revisited the upper floors of the dungeon multiple times without delving down (this is visit #3). Upon revisiting the dungeon within 48 hours of leaving, the many, many Kobold corpses we'd left behind were gone and there was no sign a fight ever took place.
In this most recent visit, we delved to the third floor. The first two floors were wide open & organic caverns, but the third floor's surfaces are obviously unnaturally smooth and angular. There are small pockets along the walls about 30ft long and 10ft wide. Perfect for cube ambushes.
To reiterate, I'm not making the case that there is definitely a cube involved. Provided that my character is aware of the existence of cubes but they don't play significantly into his history, would it be reasonable for him to connect the dots and warn his party of the potential danger in the hopes of better preparing for such an encounter? I ask specifically for the purpose of avoiding metagaming.
Would my character logically be aware enough of a potential Gelatinous Cube ambush to provide the rest of the party with an IC warning, despite not having concrete evidence of a specific Gelatinous Cube?
