The druid's Wild Shape feature in D&D 5e says:
You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can't use any of your special senses, such as darkvision, unless your new form also has that sense.
From the warforged's Integrated Protection racial trait:
You gain a +1 bonus to Armor Class
From Exploring Eberron's Circle of the Forged Skin of Steel feature:
Starting at 2nd level, while you are transformed by Wild Shape, you gain the following benefits: You gain a +2 bonus to Armor Class...
Warforged druids may not normally keep Integrated Protection when wildshaped because the shape they transform into isn't built like a warforged, but Circle of the Forged clearly lets them keep their wood and metal composition:
While in beast form, your body is made from the same materials as a warforged; your muscles are rootlike tendrils protected by armored plates. It’s obvious to an observer that you are not a normal animal.
So does that mean if you're a Circle of the Forged warforged druid, you get a +3 AC bonus to whatever beast's natural armor you turn into? E.g. Giant spider = 14 + 1 + 2 = 17?
This seems like a big difference from normal druids, even moon druids, so I wanted to double check.
