We are planing to add few things to the event Hunting Ground in the future when we see its needed.
we will make the event calculate the party members levels and based on their levels the event will summon the monsters and the higher those monsters level the higher the power and also the higher to EXP they give and the drops of coins.
Example: Level 95-145 drops Blue Crystal>10k Coins each
Level 145>160 drops Red Crystal>15k Coins each
Level 160>175 drops White Crystal>12k Coins each
