Recently most of my stamina has been going into Pengdra Villages and varios jewel/metal dragon dungeons. Every time one is voming up that's even remotely useful (which is to say "not Metal Dragons) I time out my runs so that I can sink all of my stamina into doing it repeatedly. This is starting to feel like a waste of time, since jewel pengdras now give less than a level to any of my guys and still take up quite a lot of time and space. The thing is, if I don't do this I don't know how I'll ever level anything up. What do you think? Is commitying to multiple runs of these dungeons a good use of stamina? Maybe if I ever got good drops it would feel worth it, but I just sank 60 stamina into Pengdra Village and got my least-wanted drop on all but one floor.
I'd rather go hunt Jewel Metal Dragons, even the lowest ones. And just hunt baby Pengdras.
Pengdra Village costs 20 sta, and doesn't ensure a drop of a unless it's 2x rate, other than that, Pengdra Village consists of all the colors(except heart)/element. Considering you only want to grind and powerlevel a specific element. It'll be better to go to Technical Dungeons, and hunt Baby Pengdras/Adult Pengdras, and use a lot of your Metal Dragons for evolutions. That's why I don't trash my Metal Dragons, and even just keep them for Baby Pengdras I find.
IMO, Pengdra Village is only as good if it's x2, to ensure a Baby TAMADRA/Adult Pengdras encounter and drop in it. Other than that, I find it a less useful dungeon to hunt for exp fodder, since of non-consistent element, and sta. cost.
But who knows, it, might be only in my perspective.
Edit:Why do I prefer the Jewel Metal Dragon dungeons? Simple, it drops High and higher Metal Dragons that gives huge exp. The lowest-tier Metal Dragons are just bonuses for your Baby Pengdras.
25 sta for the Hunt, and 50 for Revenge. Both good, esp if 2x.
