Planar
Natural odd non-spell strike rolls miss a Planar Character.
How it works
Full rule
A natural odd roll from a melee or ranged strike misses a Planar target even if its modified total reaches AC. Strikes generated by spell effects ignore Planar. Advantage keeps the highest even result if one exists; disadvantage keeps the lowest odd result if one exists.
At the table
Example
A natural 17 plus bonuses reaches AC 25 but still misses a Planar target when the strike is not from a spell.
Watch for this
Common mistake
Planar does not protect against a strike produced by a spell effect, including a delayed spell effect.
