Hey there! I'm researching the power of Heroes, and boy do I need lots of Skill Points for it! Do you want to donate yours? If things go well, you can earn additional SP! Interested? Here's the trick.
This research requires 100,000 Adena and 500,000 SP. If my experiment is a success, I can pay you in double the SP! But if it fails, say goodbye to the SP! Oh, and no refunds for your Adena. It's necessary for my research!
And don't die! Or else you will lose the buff I give you, and lose out on rewards.
And I'm kind of a night-owl, so don't expect me to be around to reward you in the daytime.
Well, what do you say? I'm at the end of my experimental stages, so all that's left to do is to inject some SP into either the Flask of Darkness or Flask of Light. Here, I'll let you pick.
