Crumbling Relics are Lir only.
Aged Relics - Shalemont
Tarnished Relics - Stonevale
Silver Marks are Stonevale only.
Silver marks seem to be very very rare, after farming to update fashion in stonevale, I received 10 tarnished, 37 bronze marks and 4 silver. There is no point in getting any more bronze, I already have the fashion sets that I can get and more than enough to get the other tiers if I could get silver marks. Perhaps tarnished relics are easier to get than silver marks? This doesn't make any sense, by the time I get enough silver to buy expert fashion tier, I should have enough tarnished and bronze to buy everyone tier one fashion and the level three bear drops.
I think the coding behind silver marks is like this: A% chance to receive a mark. When you manage to hit that A% chance, you enter a separate Random Number Generator. Out of that RNG you have B% chance to get a bronze mark, AND C% Chance to get a silver mark, with silver obviously being a value rarer than bronze. That value needs to be lowered. And i think if the system was changed to make separate drop tables of silver and bronze, silver would be a lot more common. It seems silly to make it rare to get a mark, and then make it rare^2 to get a silver mark. That's just my hypothesis seeing as the rarity of silver marks is through the roof.
Yes keep in mind, I caught over 6,000 tench, 3,000 beams, 2800 trout, 500 catfish, 67 king salmons, 47 giant catfish, 68 golden trout, 3000 chubs. 38 bronze, 4 silver, 13 tarnished relics. Rare would be an understatement. Now that I think about it some of the bronze may have been caught in another zone. They definately need to fix the silver token drop rate. Unless I fish nonstop from now till next year I may get enough to buy one color complete set in expert.
