The only "profit" you make is by gathering your own seaweed or sand. The spell itself makes a fractional amount of money and xp, but only if you sell the glass. If you make it into orbs, there'll be an opportunity cost. So you could get your levels all by the superglass make. That's 45,750 glass you'll have to make, or over 2.5k casts and banks. Not really worth your time, as it could have been spent killing dragons or whatever you do to make money. Now back to making orbs out of glass. Let's crunch some numbers. Glass = 401 Orb = 280 Cost = 121 XP = 52.5 Cost/XP = 2.305 Consider green dragonhides with SC needles. 3 Leathers = 5436 Body = 4545 Cost = 891 XP = 372 Cost/XP = 2.395 So leathers are more expensive, right? Yes, but MUCH faster (at least 2x), even with the time it takes to get the needles. In the time you save, you could make back that fractional gp loss.
