Nice update! Sorry to hear about your health issues. Hope things get better for you.
Makes sense that we'd be assigned a partner, not something I'd anticipated though.
Hmm. Echolocation, I suppose, from the clicker? Could be a neat trick. Though, it's something we could use with our mechanical ability, hypothetically? Make a spring loaded trap/device that clicks at regular intervals and we could use the clicking mechanism that the clicker uses, plus not give away our position like it does.
Maybe:
[x] Dissection: It's difficult to counter something you don't understand. Trap and kill a clicker and attempt to learn how it uses clicking to hunt from its body. If it detects motion, a mechanism that mimics attempted burrowing into the trunk might be enough to lure it into an ambush.
