GM Tips: Using Adult Bronze Dragon

3 tips available

When using Adult Bronze Dragon in your D&D 5e campaign, consider these tactical approaches:

Flight Control Strategy: Target flying creatures with spells like 'Hold Person', 'Web', or 'Grease' to ground them. Without flight restriction, they can escape melee range easily. Consider area denial spells below their flight altitude to force them into disadvantageous positions.
Aquatic Combat: This creature can swim at 40 ft. It has advantage in water environments. Consider fighting on land or using water-based spells against it.
Lightning Damage Awareness: Lightning attacks often have long range and high speed. Advise players to use cover and avoid metal armor/weapons. Water surfaces amplify lightning damage - avoid fighting near water.
