The NPC that sits in the bandit camp at lvl 20 wildy will now offer to sell you Chaos and Death runes through menu options.
Buy 10, 100, 1000 at prices 750 per death, 350 per chaos.
Prices are higher than market value for a reason. We hope that it doesn't become the default method for buying runes, just a last resort when no runes are in the market. People are still encouraged to collect and sell runes for below store prices, which will result in faster selling and everything.
Blood runes were not added -- however, Hobgoblins, Ice Giants, Moss Giants, Fire Giants, Red Black and King Dragons, Demons, Otherworldly Beings have all had the amounts and rates slightly adjusted in order to provide more runes (and adjusted rune/dragon drops too as some numbers were off).
