She can damage the Knight or the Squire, but not both. She can cause damage to the Knight (through the remaining armor) and the Squire (through the helmet). She cannot cause damage to anything, because the "suit of armor" as it existed is no longer an "object" (and perhaps it is now three different objects). If the druid does so, what happens, and why? On the druid's next (subsequent) turn, she can "use a bonus action.to cause this damage again." On the Knight's Squire's turn, his Squire, who is in leather armor, picks up the Knight's helmet (free object interaction) and puts it on (use an object). In just 99 more rounds he can finish doffing his armor. On the Knight's turn, he removes his helmet (free object interaction) and takes off his gauntlets (use an object action) and casts them aside. Regardless of the results of his Constitution Save, he cannot 'drop' his armor on the druid's turn. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor." We know from their being referenced elsewhere that gauntlets and helmets are objects in their own right.Ī druid, on her turn, casts Heat Metal on a Knight's armor. It "consists of shaped, interlocking metal plates to cover the entire body.

Plate Armor is a suit of heavy metal armor. Heat Metal may be cast on "a suit of heavy or medium metal armor".
