As a long time LARPer, I recommend carrying a flag on a pole to your LARP Sessions. They are generally legal to carry nearly everywhere, and they are very useful. Not only do they help maintain morale and show support for your side in a hectic field, they are also effective weapons. Thrust the tip forward in order to create space or deal a wound to an opponent. On the defensive, use the two ends to good effect for blocking blows. Be careful about swinging it, as this has the potential to hit a comrade next to you and leaves you vulnerable. Additionally, never leave the end extended, or am opponent may grab your flagpole from you, which sucks. Anyway, I hope you appreciate my LARP tips. More are on the way.
I do actual LARP as well, but mostly just with my friends so I don't know any orgs
