Fireblend gives you Fire Bolt lvl 3. It's an easy way to level a merch. Just switch to full int and FB some muscs out in Rachel. After hitting BS or Alch, you can then reset to your desired build. It's a tad pricey (170k for reset at lvl 65, I believe) but wayyyyy faster than the speed at which merchies kill (also a lot cheaper than mammo'ing your way to BS/Alch). xD
