There are some rules we will always have trouble remembering and have trouble finding the text to support, but are still common aspects of the game. I intend to put those in this thread. Mostly they will just be quotes from the rules directly or from the Sage Advice column.
Which is correct in the Dungeon Master’s Guide, the rule for scrolls or the rule for a spell scroll? They’re both correct. The rule for scrolls (p. 139) is for scrolls in general, including a scroll of protection, and it allows you to try to activate a spell if you’re literate. The rule for a spell scroll is specific to that type of scroll and introduces an additional requirement: the spell on the scroll must be on your class’s spell list for you to read the scroll.
A spell scroll can be named in a variety of ways: spell scroll, scroll of X (where X is the name of a spell), or spell scroll of X (where X, again, is the name of a spell). No matter how its name appears, a spell scroll follows the same rule.
For you to meet a spell scroll’s requirement, the spell on the scroll needs to be on whatever spell list is used by your class. Here are two examples. If you’re a cleric, the spell must be on the cleric spell list, and if you’re a fighter with the Eldritch Knight archetype, the spell must be on the wizard spell list, because that is the spell list used by your class.
Pillows are designed for relaxation. If they are fighting, what hope do we have?
