Wait nevermind I just saw where the 2d6 comes from in the combat logs. Strange that the sneak attack tooltip wouldn't reflect this ?
yeah you get the 2d6 at 3rd level and it jumps to 3d6 at 5th and then every 2 levels another 1d6. They don't really label it properly but it's there.
As for the Range Heavy Xbow/Longbow is supposed to be 30 Meters and Light Xbow/shortbow is supposed to be 24 meters. Not sure where 18 meters came from but its interesting that it will work slightly outside that range and with the 24m of darkvision assures that you will be able to range sneak attack.
I experimented with Sunwalkers Gift to see if it would do something similar but it appears to only illuminate objects to the regular darkvision range of 12m.
