The updated Warforged's Integrated Protection trait, as detailed in Eberron: Rising from the Last War (p. 36), now states:
Your body has built-in defensive layers, which can be enhanced with armor.
- You can don only armor with which you have proficiency. To don armor [...]. To doff armor [...]. You can rest while donning or doffing armor in this way.
- While you live, your armor can't be removed from your body against your will.
With this revised wording, does the warforged now count as wearing armor when they are using armor in this way?
This is important in the context of how something like integrating a set of plate armor would interact with monk features like Martial Arts.
When using a previously published iteration of the Warforged from the initial version of the Wayfinder's Guide to Eberron (which one of my players has been using), there was significant ambiguity over whether or not a warforged was wearing armor.
(That version of warforged was identical to the version in UA: Eberron Races.)
However, as the most recent iteration of the Warforged (published in Eberron: Rising from the Last War) has changed this wording so significantly, the question is worth revisiting. (My player also intends to switch to the new published version once they gain a level.)
