Immunity Idol Clues

Welcome to Patagonia, we hope you'll stay a while
But you know to make the end, that it will take some guile
And if you need some help, just in case you're wrong
Take a look around here- it may make your stay here long

Two countries make up our region, and it's anything but straight
But if you need assistance, it can help you change your fate
For when the votes are in and your name is mud
The power we have will turn your foe into a river of blood

Things getting you down, the pressure getting to you?
Need my assistance? Or are you just going to spew?
With my help you'll survive a disastrous day
While an enemy sees their head blown away
