Both of the above posts are 100% WRONG. I've been out of the loop since staking ended however during the end of its course I was staking anywhere from 50k-5million at a time. I would be happy to provide some evidence of this. You don't need to "clean" someone out to make a bit of cash. The average age of a typical RS player I would imagine is pretty young as a such you play to emotions. Beat someone and say "I got lucky", "wow, my first time winning!" or "you suck", whatever your taunt of choice is and many times people will go round 2, 3, 4 to stake again. Having said that, my personal opinion leans towards multi-pures with 1 def, 1 pray. Back in the day, I would encounter pures, def hoarders, and mixes. So building a staker with specific goals in mind is just fine. Never wear your best armor while walking around and your stats won't be as impressive. Finally, always expect a switch. Make sure you can Mage/Range, Range/Melee, or Melee/Mage. If you can only do 1, you'll limit yourself greatly. As far as I remember, Mage has a % that's passive so just having mage levels (which you can build without building hp, thus not affecting your CB level) will give you magic defense in additional to whatever defense you already have.
