I am playing in a 5e level 20 one shot and my DM is allowing us to choose a number of magic items. The Way of The Ascendant monk looked fun and I happen to own both the "Rise of Tiamat" and "Hoard of the Dragon Queen" campaign books so I decided to go with a heavy dragon theme.
I have chosen to have "The Mask of the Dragon Queen" as my Artifact, but I am unsure on how exactly it works. I know its listed as one of the "Problematic" items for the Adventure League as mentioned in this question, but I figure that is more for balance issues. The item description itself says
... While you are attuned to and wear this mask, you can have any of the properties from any one mask. Additionally, you gain the Damage Absorption from each of the five dragon masks, and you gain five uses of the Legendary Resistance property.
The "..any one mask." refers to the 5 dragon chromatic dragon masks that make it up, and have a lot of various buffs. All of the specifics can be found in the free PDF supplement Here but the important one to my question is Damage Absorption.
Damage Absorption. You have resistance against the mask's damage type. If you already have resistance to that damage type from another source, you instead have immunity to that damage type. If you already have immunity to that damage type from another source , whenever you are subjected to damage of that type you take none of that damage and regain a number of hit points equal to half the damage dealt of that type.
My questions are:
- When and how can I change the mask that is 'active'?
- Does the 'active' mask give immunity to its element since the Mask of the Dragon Queen has all the properties of each mask and the properties of the 'active' mask?
My best guess for #1 is I choose when I attune to it, but I cant find anything official. I even tried buying the item on DnD Beyond to see if they mentioned it there or had implemented it in some way. Unfortunately it doesn't look like they even tried.
For #2 I would guess not because the ability text specifies "... another source..." but figured I would check anyway.
An official ruling or Rules as Written/Intended is best, but experience with the item itself is also appreciated. Im not the type to try and min/max and am confident that my DM is ready to kill us anyway, but I'd like to avoid confusing him if possible.
