Within the dozens of minutes, it took for Kain to go through the Black Mission questionnaire there was a new addition to the Gold Missions window. One that rewarded 400 credits and was one of the few that rewarded so many credits and didn't require hunting a spiritual creature more powerful than he could handle alone.
Although it wasn't the full amount that he wanted, it could get him more than half-way there. Maybe he'd run into more than one orange-grade spiritual creature along the way. Or if he was okay with rushing Bea, he could pay for just 40 minutes but considering that the probability of her getting the best evolutionary results was already below 50%, he didn't want to add any mental stress to her by rushing her during such a sensitive time.
The new Gold Mission Kain recalled seeing on the Silver Mission board earlier worth only 40 credits.
