Berwil's Analyze Magic

For the duration, you sense the presence of magical effects within 100 feet of yourself. If you sense such effects, you can take the Magic action to see a faint aura around any visible creature or object in the area that bears the magic as well as any ambient magic in the area, and if an effect was created by a spell, you learn the spell’s school of magic.

In addition, if you spend at least 1 minute studying the magical effects, you gain advantage on one of the following checks

• Arcana checks to understand the nature of magic affecting the area you are in(i.e. spells like Forbiddance or regional effects of legendary creatures)
• Spellcasting ability checks to cast dispel magic on the effects studied
• Arcana checks to recreate enchantments on magic items

In addition, if a wizard spends one minute per spell level studying a spell scroll of a level they are able to cast, they can add that spell to their spellbook. Adding a spell this way increases the time by one hour and the cost by the cost to scribe that level of scroll(as per the crafting equipment section of the players handbook).

The spell is blocked by 1 foot of stone, dirt, or wood; 1 inch of metal; or a thin sheet of lead.
