Looking at the pricing guide, the suggested range for a gelatinous is 350-400k.
I'd prefer pure rather than ectos but will take them at a 4.3e=1K ratio.
In game, you may contact Aliana Stoneskye.
Starting bid at 330K, running for 48 hours.
If someone offer 400K in game, I'm selling it and will edit this thread to note the sale. Thanks for your time.
