Taming mobs for a certain number (15-50) of times
Beetroots should be sellable to shop at 1 each. Chorus fruits should be sellable to /shop at 5 each.
Daily quests should be easy to do with less reward (1.5k each instead of 2k each. 1 quest point each). Some good options are:
Better Economy
All players will receive 1000 as long as they have dealt damage to the dragon.(Change to: Players will receive money based on the amount/percentage of damage they have dealt to the dragon.)
Making mob drops sellable to /shop.
Purchasable Advertising Slots
Dragon breath can be sold to /shop at 400 per bottle.(The price is not high, since one dragon needs four crystals which need 4 ghast tears. Ghasts tears are very hard to get without /fly. The average price for a ghast tear is around 100k.)
“Killing the Ender Dragon”
Making the PvP Arena similar to the current /duel arena, which is on 1.8, and leave the other parts of the server unchanged (but with the inventory and armors carried instead of the default kits)
