actually crystal war is 20 years in the past, where the tri country expidition into xarcabar was 30 years in the past. Also if i recall dynamis lore... They are rements of the shadow lords memories of the crystal war. where the second tier dynamis is his dreams based around diablos. (guessing)

but honestly I agree with the suggestion. I wouldn't rely on players trading for coins. People are too gil centric for bartering.

as a person who did dynamis @ 75 when it was launched, currency was fairly easy to get, just people sold it via LS banks to fund runs back when the item needed was $$$ unless ur LS charged a fee per run. So an exchange npc would be pretty cool. The weapon itself takes so much time to get already seeing someone with it was rare.. Like back whenh garuda was a server.. only I recall actually having any relics was WWCC an elvaan. other them him i didn't really see anyone with relic weapons.
