Open it up, leave the encounters, allow people the play with mechanics in a consequence free environment. Wanna run gauntlet? Put a centurion at each runner plate and when killed it spawns an orb for someone to just practice their running, have the psionic charges in each 3 by 3 wall randomly show up as if it was being stood on and shot outside, let them keep going as well to do all 3 and see how the run changes each time. Bathers could stay the same except chains dont lower allowing a single person to lock all of them and shoot at the lamps. Idk how to allow practice for dogs and castellum could just be constantly running for people to gather standards and what not and see how that works. Public events could also just be the actual raid encounter without wipe mechanics.
