Hey there,
The hit strength due to both your stamina bar(which showed in the left-top corner) and another player's, weapons, hit part, and other factors.
Besides that, everyone has the same stamina and HP, which would lose because of the hit, gas, fire , sea water, cold and so on.
Please save your stamina and protect your HP during the game.
Hope such an explanation can solve your question.
You can also visit our official forum[https://forum.partyanimals.com/] to discuss strategies with other players.
Thanks for your support!
Best,
Party Animals Support Team
