Relic is a huge gilsink. Every time a weapon blows up there is Gil removed from the economy. The economy consists of not only Gil, but the items that have a Gil value also. When we talk about Gil sinks, for whatever reason, we only reference the very rich. But if I farm 2 million Gil, spend that 2 million on a weapon, and proceed to blow that weapon up by attempting a meld, that's a 2 million Gil item that no longer exists.
