It will need a custom GUI when u type /quests. There will be two types of quests; PvP and PvE. Then there will be 6 sections such as kills per life or taming. Then after that there will be 4 different objectives in each section. When u complete a quest it will say it in chat (not broadcasting just to the player) and u can type /claim reward to claim the reward for completing it. Some quests will give u custom abilities but if u cant then i will have someone else do it.
