[0.99] Dat Pendant

what does that tim's secret lab thing do? i didnt really get it from the description. also didnt see it in the cs

It's a 100% potential scroll. Gives a regular item potential lines with no risk of blowing it up.
And it's not in CS because it's probably going to only be available for a week or two sometime in late July or early August, "special event get them before they're gone" type of thing. Like Pam's and Vega's.
