First, ensure you have a clear and focused intention to heal the dragon. Approach the creature with caution, as dragons can be unpredictable when in pain. Stand near the wounded area and place your hands over it, without touching the dragon's skin. Close your eyes and take a deep breath, clearing your mind of any distractions. Visualize a calming, healing energy flowing from your core through your hands and into the dragon. Recite the words 'Iashna Velara' with conviction, allowing the magical energy to envelop the creature. Gradually, the dragon's wounds will start to knit together, as the poison is neutralized. Maintain your focus until the healing is complete and the dragon is free from pain.
The wounded creature is a rare species of dragon that has been injured in battle. Its wounds are deep and it's suffering from a poisoned arrow.
