Dododex users say:
Watch cave ceilings carefully, as Megalania can blend into the darkness and drop down unexpectedly. Avoid being bitten because it inflicts Mega Rabies, which rapidly drains health and stamina; carry a cure such as Lesser Antidote or Wyvern Milk. Use ranged weapons to kill or quickly tranquilize it, and be cautious around cave hazards while fighting.
