Economy tuning: upgrade chests come twice as fast, the shop is half price, and copper ingots can be sold.

Upgrade chest XP cost halved: 1000 → 500 One Upgrade Chest per 500 points of actual experience (actual experience = raw XP × your XP Drop %, which also includes the Root Retreat blessing's +10% per stage). Chests arrive about twice as often.

All shop prices halved Common / Advanced / Rare / Legendary / Bond artifacts and slates: 250 / 500 / 750 / 1000 / 1500 (was 500 / 1000 / 1500 / 2000 / 3000) Potions (Common / Advanced / Rare): 25 / 1500 / 5043 (was 50 / 3000 / 10086) Artifact Chest · Slate Chest · Upgrade Chest: 750 (was 1500) Sell prices are derived as "buy price × 30%", so they halved as well; the Negotiation discount and the rounding rules are unchanged.

Lucky Medal: leaf payout per potion halved Buying a potion in the shop now grants +50/75/100 leaves instead of +100/150/200 (levels 0..2).

Copper ingots can be sold to the shop Put copper ingots into the shop's sell slot and press Sell to get 1 leaf each (the whole stack sells at once). It is a sell-only item: the shop does not stock it, so its price is a fixed 1 leaf rather than 30% of a buy price.
