Landscape of Spell Lore

Wizards who cast landscape of spell lore on themselves instantly become aware of all spells as they are being cast in a 25-foot radius around them, as well as the nature of this magic: general effects of a spell being cast, level of the spell, whether its power originated from a magical item, etc.

Characters can tell the minute another wizard in the area of effect begins casting a spell, allowing them to react before the new spell takes effect. (Its effect may take place outside the 25-foot radius, but the caster must remain within this area to be detected.) Landscape of spell lore does not inform casters of magic that took effect before its casting.
