I've accumulated 100K runes from playing events since Gideon 3 was released. Did not even play much story mode, just went back to get some of the tertiary objectives for the crystal reward.
Phase said: TG is almost 1500 runes a day. In a month that's roughly 40k runes just from 15 minutes of TG a day. And you get the 450 crystals too. I don't think runes are going to be a big deal to get if you are doing daily TG.
Twee said: @Phase. I know people don't just play tg but at that rate it takes a month to buy a mono pw but 2 months to level them. What about duel color or heaven forbid a tri color, 3-4 months?
