Re: Chapter 5 - OOC
After looking at the character sheets, Yuu could rummage through his magic utility harness and piece together some sort of mental communicator device (ie. a telepathy gadget). This will require a skill check (Knowledge: Technology), with a DC of probably 12... so in other words don't bother rolling since Yuu has 12 ranks in that skill.
It'll just take a few moments to get the device set up, and it may take a little while for Yuu to get the hang of mental communication since he's not done telepathy before. Hence he'll have to focus to prevent his mind reading from wandering through other surface thoughts in people's minds. Thus we'll need a Concentration check with a DC of 25, since this is his first rodeo and he's dealing with 2 different minds.
If you just want to take 10 on the concentration check you can since this is not a combat situation, but it does mean that you guys will spend about 5 additional minutes helping Yuu get accustomed to mental communication.
So yeah, you guys can have a conversation without the others hearing... unless Lasrane is able to listen to your thoughts without even seeing you! Even while he's sleeping!
