I guess this is your first time to fight with an event NPC dragon. Legendary Dragon is one of the most powerful dragons, but in this case, you should not use it for the battle. If you've noted, the HP of NPC dragon is always as 125% of your dragon HP, so the stronger your dragon HP, the higher NPC dragon will have. Therefore, best chance is use low level dragon, but not too low, which also has no weakness against War/Flame of course. Then the distance between your dragon and Thor won't be matter
