Trying to set up bots to set up a dueling tourney with friends (sounds dumb but its just easier when I dont have to control every character) is there any way to get a Rotation bot to try breaking LOS on casters? Thanks.

It's possible but hard to implement. You would have to come up with an algorithm that tests positions around you and find one that is both reachable by the pathfinder and out of sight from your target. Once it's done you'd have to stop the rotation and move you character there.

You can use TraceLine.TraceLineGo to test LoS between positions and your target. Be aware that it's counterintuitive as it returns false when in sight, and therefore true when out of sight.
