Jewel and Stone are required items for getting a card through Card Trader. In order to get those items, you need to exchange cards with the same rarity and same attribute as the ones that you want to acquire or meet "Stage" requirements.
Jewels and stones are one of the duel rewards. Basically, having a lots of duels and scoring high are ways to earn those items since you can get one reward by 1,000 score. For example four rewards appear when your score is 4,000 or more and less than 5,000.
You can convert your cards into jewels and stones at the Card Catalog. What trader item you get is based on attribute and rarity of a card you convert. For example, a normal rarity spell card can be exchanged with 100 gold and a Stone of Spell.
Jewels and stones are also reward for completing some missions, although you cannot obtain many of those items by doing that.
I have too much Rare jewels and I need to find a way to spend them. I'm already spent too much too much money on cards in order to get rid of the rare jewels. I need to find another way to spend rare jewels without spending any more money. at least find a way to convert the rare jewels
You can upgrade the cards to glossy and prismatic. That's what I do. With the Kc Cup coming some cards you can upgrade for a limited time
I have max R jewels currently and more in my giftbox about to expire. What's the best way to use them so they do not go to waste. I don't want to use it on card trader bc it also requires other stones and coins to be spent with it. I only want to spend the R jewels. Is that possible?
If you have max R jewels, you should have a ton of other jewels too. Don't be afraid to spend them. If you've never felt the lack of say, WIND jewels until now, then you shouldn't be lacking of them in the future too. It is the only way to spend R jewels.
but to attack on the turn you summoned it you need 3 monsters, and that is not all, it gets only to 2600 attack, which other lvl 7 monsters already have from the beggining, sure using pinch hopper can easily summon it, but i feel empress mantis does the job, and dont forget insect princess with paricide parasit.
insect queen works well with pinch hopper meaning you only need 2 monsters and that's pretty noob if you think it's useless. The good thing about the legendary fisherman is that if you have a monster with incredible defense e.g. labyrinth (3000 defense) then you can keep attacking your opponents monsters
