If you clicky here you'll find a small mod which has a demo of the implementation of Climb, Balance, Jump and Escape Artist (with Swim to come) that I've been working on. It's a basic NWN2 mod which uses Move Silently as a placeholder for the ACR skills but shows how I intend everything to work. I don't want to say too much more than that because I'd like feedback on whether it's obvious what to do and so on. Only thing to say is that you will get a prompt about whether to continue once you click on any of the skill-use icons.
Abuse, praise and good ideas welcomed
