The adept is always subject to controversy, right now the price will be a bit elevated despite unsealing going back to being CORRECT. Limiter is probably 15, adept due to demand and lazy ass players will probably range up to 35 in value or more depending on if seller is holding out for maximum shekels.
I agree, units aren't even as bad as unsealing weapons since you could stack up more limiters or lores to unseal together. 15pds for unsealing limiter is pretty lol. Would rather buy 2 limiters at that price.
From what I gather Adept is roughly 25-35 pd value and Limiter is roughly 20-30 pd value.
We might need more testing to determine the difficulty of unsealing, as well as more suggestions for optimal builds and quests for killcount.
202 kills from about 4min(taking in walking and room create) when I do MASe4 up to first Girta. Stack that with 3 other unsealing units and you can get a lot of kills in. BtH may give you more kills but costs meseta.
