Telepathy for Dummies (5e Equipment)
From D&D Wiki
Wondrous item, uncommon (requires attunement by a spellcaster)
A cheap-looking instructional book, written with very simple prose and containing plenty of pictures, that claims to be able to grant psychic powers. During a short rest, you can choose to refresh your memory of the books' contents, following the same process as the initial attunement. For 1d6 hours afterwards, you have a +2 bonus to spell attack rolls. As a bonus action, you may concentrate on trying to remember what you learnt by making a DC 15 Intelligence check; on a success, you gain a +1 bonus to spell attack rolls until the end of your next turn. These bonuses may stack.
