One of our players is using the Pre-gen Rogue that came with the Dead in Thay adventure.
The Level 6 Halfling Rogue has a Dexterity of 19 (+4) and Expertise in Acrobatics (+5). Does this mean he has a +9 on all Acrobatics checks? Or is the +5 considered the cap for check bonus on something a Rogue has expertise in?
In other words, does the expertise bonus stack?
It makes sense that it would stack, but I want to confirm since a +9 seems like a huge bonus on checks.
Thanks for any advice.
