IF I have multiple computers with AI for instance my tier 1 computer and my tier 2 after reaching level 3.

Can I roll 2 separate skill checks each with their respective bonuses?

Also in the rules is says AI can communicate in plain language. I'm not sure what the limitations are on plain language. Does the AI know all the languages my character knows similar to the mechanics AI, or do I designate a language at creation.

For instance if I want a computer to attempt a skill check with a creature that speaks a language that my character also speaks.

Hey found a potential typo and if it's not a typo I'm looking for rule clarification

RAW

Each model of squirming entrails functions differently when extruded: mk 1 squirming entrails help you keep your balance, so you don’t take the normal penalties to attacks or gain the flat-footed condition when you are off-kilter, and you gain a +4 circumstance bonus to Athletics checks to balance.

Balance checks are under Acrobatics, I was wondering if this is a type or if I'm missing some other sort of balance check that uses Athletics.

Thanks
