Monster Hunter Rise

Below is my guide on how to obtain the "Prismatic Chalice" achievement, as well as additional information that I believe you will find useful if you are going for this achievement.

In order to obtain this achievement, you must complete 50 quests in the Flooded Forest Locale. Any quests completed will count towards this achievement, also, progress towards the "Prismatic Chalice" spans across: Low/High Rank Hub Quests, Village Quests, and Low/High Rank Event Quests.

First off, this achievement will most likely unlock with time, so you may not want to start off grinding for this. Instead, I would recommend you wait until most/all key quests for Village and Hub respectively are completed. Here are the different quest values for the different types of quests which take place in the "Flooded Forest" locale throughout the game.
There are:
-Event High Rank (7)
-Event Low Rank (0)
-High Rank Hub (14)
-Low Rank Hub (8)
-Village (8)
The above listed will total to 38 quests, meaning you will only have to complete 12 additional quests in the "Flooded Forest" locale. If you end up hunting monsters multiple times for Gear/Weapons/etc. you may find yourself closer to 45 or even the 50 quests completed mark.

If you are already in High Rank, and find yourself wanting to get this achievement even quicker: You are able to go back and do some low rank hub or village quests; the monsters will be easier to hunt with higher tier gear.

Here is a recommended list of the easier quests to farm:
-2* Low Rank Hub Quest: "Hide, Hide, Hide!"
-3* Village quest: "Breath of the Past"
-5* High Rank Hub Quest: "Flooded Forest Fiasco"

I have excluded the Event Quests from this guide, as none of them are particularly easy or fast to complete. Thank you for taking the time to read my guide! Happy Hunting!
