Talk:Jungle Key Mold/@comment-24116732-20131101013112

I'm pretty sure that this and the other key molds don't drop unless Plantera has been killed. It's basically a certainty that the Corruption Key Mold doesn't drop if a mechanical boss hasn't been killed, as I farmed meteor heads until I got 180 gold, 83 banners, and 348 meteorite ore. Looking at the average money dropped (80 copper) and the other drop rates (based on the key's former drop rate of 1:4000), I should have gotten around 32 gold,  20 banners, and 80 ore from farming the key mold (which is fairly consistent with my experience farming the Crimson and Frozen molds on a world where I beat Plantera). It's extremely unlikely that I would get over four times those amounts without getting a single mold. I also idled to 39 gold, 16 banners, and 86 ore after killing Skeletron Prime, though that still is within a reasonable probability for not getting the mold. In any case, I think that the possibility that those conditions must be met should be taken into account.
