Natural wonders are out, too expensive and nothing with time or creation. Good to see price range though.
The only 4 treasures I see as worthwhile are the giant's armor, everbloom, pair of glass warhammers, and the core geode.
As for pills nothing look like what we want, at all. maybe some heal pills? Frankly I don't see us needing any pills for the closer fight at all. Maybe level up the spear again or buy an anam regenerator for cultivating? it'd be a better idea to just buy em from Shouxi, his are better.
