<li><strong>HIDE</strong> only rolls against creatures that are currently <em>observing</em> you. If a creature already considers you hidden or undetected, you simply retain that condition — HIDE does not improve your state from undetected.</li>
<li><strong>SNEAK</strong> requires cover or concealment at <em>both the start and end</em> of your movement. You move up to half your Speed.</li>
<li>Taking any non-<em>unobtrusive</em> action while hidden immediately makes you <strong>Observed</strong>.</li>
<li>A <strong>Strike</strong> from a hidden or undetected position makes you <strong>Observed</strong> after the attack (target now knows your location).</li>
<li>A <strong>STRIKE</strong> from a hidden or undetected position makes you <strong>Observed</strong> after the attack (target now knows your location).</li>
<li>An <strong>Invisible</strong> creature that critically fails a Sneak roll becomes <strong>Hidden</strong> rather than Observed, since it cannot be seen.</li>
<li><strong>AVOID NOTICE</strong> (Exploration): Roll Stealth to start an encounter Hidden or Undetected rather than Observed.</li>
