-Offhand entry applies actual native maximum health `min(10 + CON, native health limit)`, resumes saved remaining character health, and shows public blue particles.

+Offhand entry applies actual native maximum health `min(10 + CON, native health limit)`, resumes saved remaining character health, and supplies the recurring blue active-character aura to native viewers who opt in with `/fantasyparticles players on`. The account-owned aura preference defaults to off; `/fantasyparticles players` reports it and `/fantasyparticles players off` hides only this recurring aura. The independent, default-on `/fantasyparticles all [on|off]` preference durably controls every explicit Fantasy Stick particle for that account without changing nearby players' delivery, sounds or gameplay. Turning `all` off temporarily takes precedence without overwriting the saved `players` choice. A fresh character's saved health starts full. CON has no gameplay cap; high values do not reject entry. Native damage/healing rules remain in effect, with the existing party/mixed-mode protection. The book reports current native health rather than waiting for an exit save.
 
 `NativeMaximumHealth` owns only the effective-value cache/dirty callback of that player's existing native maximum-health instance. Base values, modifiers and native potion expiry remain owned by their original sources; nothing is copied back from an old modifier snapshot. The native player health methods and client attribute snapshot are tested. This adapter uses **pinned Purpur 2618 internals**, including private fields; a detached startup probe exercises installation, recalculation and removal before gameplay is registered. Runtime upgrades require renewed native compatibility verification, not a guessed fallback or global attribute-limit changes. Matching native health scaling displays the real fantasy maximum, not a separate virtual health pool; a later unrelated display-scale change is preserved on exit.
