Does the Vrock's spore ability inflict both the "poisoned" condition and poison damage, or just poison damage? The wording seems unclear.
The target is poisoned
Each creature in that area must succeed on a DC 14 Constitution saving throw or become poisoned. While poisoned in this way, a target takes 5 (1d10) poison damage at the start of each of its turns.
The target is poisoned and suffers additional effects as long as they remain poisoned. A similar wording exists for many spells that inflict the Charmed condition and some additional effect, for example Dominate Person.
