During Ursoth Event, 5 energy kits is 25 platinum. Let's say I have 100k. After using it, I need to buy platinum. Let's say I'm going for LB and im doing 1,000 runs. 5*1000=5,000 platinum which is $267 (Thanks for the correction Zylx)That's just 1,000 runs, and that's considering you have 24 hours of the day, and you have the top gear.
