Big ol' post below:

Every LARP has a different system, which in our game is light-touch(1) and kinda light-hearted. We use latex weapons like those from Forgotten Dreams and Mytholon (two manufacturers I know of off hand), and there's a hit point system, and vocally called damage and skills with different effects.

Example: Hitting an opponent and calling "Strength 5" indicates to the opponent that they need to take 5 steps away from the attacker in the direction the attacker chooses. They also take basic weapon damage of 1 HP in this transaction.

While every LARP has its own system, there is a lot of overlap because of the limitations presented by a physical (ie. in-person) system. You can do a way larger swath of things in a tabletop.

Look for LARPs in your area online, and I'm sure you'll find a few.

(1)Different games handle it differently, but we have players stemming from single digits to upper double digits, and we try to be accommodating to the needs of a diverse age group with varying degrees of disability.
