Make the item sockets at Item Merchant Geric in Alberstol Ruins cost a lot more than they do right now. Make the t5 ones cost 1G each, make the t4 ones cost 50g each. Also, make the default option be to buy only 1 instead of 50 to avoid major slip-ups. Currently, you can buy t5 empowerement sockets for like 1.2g each. These soc emps are essential for cap players and will always be in demand. Increase their price in NPC shop to make a decent gem sink.
If yall want, add t3 ones in the shop and make them sell for 25g each, as those are in demand as well but they're not in the shop.
Don't add 1HKO gems in the shop
