Welcome! You’ve come to the right place - So many of my questions were answered here before my first event, and now hopefully I can pass on that wisdom to you!
Absolutely, definitely, 100% try and make something OOC to bring with you. Like you say it’s a great way to get a conversation flowing. It is also an easy way to get hold of plot or story! There are loads of things you can make, I personally have made some necklaces to sell IC. What I will say is that it’s much more likely that you will be trading for IC coin, as most people will be carrying this as opposed to Barbarian money (OOC cash). Most of your trading will happen by exploring the various nation camps, and really OOC money only really changes hands in the trader’s square and tavern.
There’s no specific answer for how much LARP stuff costs. I went really basic to my first event, but ‘basic’ is subjective, but to give you a rough idea, a basic tunic, belt, trousers, boots and cloak just under £100. Obviously you get what you pay for but my outfit served me very well all weekend.
I would advise against going for archery on your first character as, like you’ve rightly pointed out it’s more expensive and you have a chanced of losing arrows, as well as the poundage of LARP bows is not the same as what you are probably used to. Each arrow varies from around £6.50 to £9.50 but I’m sure if you shopped around you would find deals. HOWEVER. You need to make sure the arrows (and any weapons for that matter) adhere to Profound Decisions rules. My advice for this is to buy your weapons in the field, as the traders are highly reputable. I bought a sword online before the event and I knew as soon as I saw a weapon at the event that mine would definitely NOT be suitable!
A lot of people do get their gear from charity shops - belts were by far the easiest thing for me to find as most charity shops have appropriate ones! But you could easily find cheap materials and make something. Should you decide to join Wintermark for example, we’re very furry! I used a women’s fur shawl as a mantle for my character and it worked a treat.
It’s all about trying things out really. You have the added bonus of quite a big gap until the next event to save up, and experiment!
And I would also recommend camping OOC for your first event. It was recommended to me before mine and I am so glad I did that - IC camping is a whole other level of immersion, and you don’t have the luxury of being able to store OOC items or be near your car!
Hope this helps, if you have any other questions feel free to give me a message.
