Talk:What Stalker?/@comment-75.72.7.59-20130804154113/@comment-166.147.72.23-20130818221752

Lets calculate: Chance of stalker Chance of successful killing of stalker Chance of drop (x3) Chance of drops (and amount needed) for crafting materials to craft each BP Chance of alert missions for potatoes (x3) Chance of drops (and amount needed) to craft each potato (x3) Need to buy 3 inventory slots with plat Credits needed to craft all Time needed to craft all (6 BPs plus need to buy inventory slots)

So put all that together plus the fact that at least IMO these are the best weapons in game... I think it's the best warframe purchase you could make.
