Understanding

When a creature casts a spell, you can spend a reaction to try to gain the understanding of the spell. Make an Arcana Check against the targets passive Arcana, which is 10 + their Arcana modifier. If successful, you gain the following information;

• The spell’s School of Magic
• The spell’s base level
• What level the spell was cast with

You are able to share the information with all within hearing range, as part of the reaction. If you know the Cantrip “Message”, you can instead use that to send the information directly to 1 person within the spells range for free.

If a creature doesn’t have a specific Arcana modifier, use their Intelligence modifier instead.
