The lightfoot halfling and wood elf traits-Naturally Stealthy and Mask of the Wild-do allow members of those subraces to try to hide in their special circumstances even when observers are nearby. Normally, you can’t hide from someone if you’re in full view. A lightfoot halfling, though, can try to vanish behind a creature that is at least one size larger, and a wood elf can try to hide simply by being in heavy rain, mist, falling snow, foliage, or similar natural phenomena. It’s as if nature itself cloaks a wood elf from prying eyes-even eyes staring right at the elf! Both subraces are capable of hiding in situations when most other creatures can’t, but neither subrace’s hiding attempt is assured of success; a Dexterity (Stealth) check is required as normal, and an observant foe might later spot a hidden halfling or elf: ”I see you behind that guard, you tricksy halfling!”
