ATTUNEMENT EXCEPTIONS- All character classes have an armor option (ex., for wizards) -So Bracers of Defense would not require Attunement.
An initiative penalty (next turn only) for ANY attack roll (melee, range, spell) of a "1".
Consuming a potion (self only) costs one bonus action for up to three declared potions "on person".
Leveling up for full level benefits requires training, measured in days required by proficiency.
If you are stable (after successful death saves), you can spend Hit Dice after an hour (ergo, a short rest) and regain hit points based on the rolls, or can wait 1d4 hours to regain 1 hit point. When recovering from Unconsciousness caused by reaching 0 hp, rises above 0 hp in any way causes consciousness to be regained. Thus, magical healing also removes Unconsciousness.- Most of this can be found in the PHB, Chapter 9 (Combat), in the Damage and Healing section, mostly in the Dropping to 0 Hit Points subsection. The Unconscious condition is covered in Appendix A of the PHB.
Expendable items have a lower appraisal value. Armor prices adjusted.
