You have begun learning to be more efficient with common practices of adventuring.

• You can use healing potions as a bonus action, instead of an action.
• You can read spell scrolls and cast the spells from them even if they aren't from your spell's list (or if you can't cast spells). To cast from a scroll in this way you must make an ability check using your spellcasting ability (or Intelligence, if you have no spellcasting ability) to determine whether you cast it successfully. The DC equals 10 + the spell’s level. On a failed check, the spell disappears from the scroll with no other effect.
• You can don and doff shields as a bonus action.
