Forbidden Insight

When you cast a level one spell or higher which requires a saving throw, you can reduce your spell save DC by 5 for that casting. If a target fails the save, divine knowledge floods your mind: in addition to the spell's normal effect, you learn two of the following about the target (your choice):

• Its current hit points
• Its physical ability scores (STR, DEX, CON)
• Its mental ability scores (INT, WIS, CHA)
• Its condition immunities
• Its damage immunities and resistances
• Its damage vulnerabilities
• Its speed and movement types
