New to the game, realistic chances on completing this by early October so I can participate in the Monster Hunter Wilds collab?

Play FFXIV instead. Here is a list of quests you need to have completed by early October in order to participate in the Monster Hunter Wilds collab. It’s nothing really, only about 1000 quests to do. Again, complete these 1000 quests by early October or you’ll miss out on the MHW collab.
