The Dragon Invasion Event is a daily event in which dragon re-spawns every 23 hours. Most of the information about the event is available in the log on the left side of the window. Please read that before going up for the event.
This is an event which I would say every one should try, at least when their heroes have become a little better so that they do some 1 or 2 damage on the dragon. There are nice gifts available for toppers, first blow and killing blow, and for the rest some prestige and copper.
But one has to be careful so that you do not waste many troops and do maximum damage.

- Dragon's Nationality - This changes randomly for the dragon, so one has to take the heroes of the same nation in which the dragon is (Persia, Rome or Greece) so that you can do 200% increased damage. Now this you already know, what you need to know is the number of troops, number of heroes and the formation for the battle.
- Number of heroes - If you have four heroes of that nation, you are good to go. In case, you don't have take rest of other nations. Do not take less than four due to the fear of loss of troops. This is because with the right formation of the heroes, you can make your same nation heroes do more damage while other heroes keep dying and hence give you extra turns to hit.
Therefore for such a scenario, the formation should be such that your same nation heroes are hit by the dragon at last. - Formation -
1 2 3
4 5 6
7 8 9
If we number the grid like this, and let us assume that you have only two heroes of same nation H1 and H2, where H3 and H4 are for sacrifice only. Also, H1 is stronger than H2.
In this case, one of the options for maximum damage is to place H1 at 2, H2 at 3, H3 at 4 and H4 at 5. With this H3 and H4 should never get a chance to hit and H1 and H2 will give maximum number of hits before dying.
If you have all the four heroes of same nation with their strength as H1 > H2 > H3 > H4, the corresponding position that I found to be best is, 7 - 8 - 5 - 6 respectively.
Give these a try if you were not using the same formations, and you will see the difference. - Number of troops - The heroes which you take for a sacrifice only, give him just a single troop to carry, because he is anyway not going to attack for such a case.
Give the best necklace to your heroes which are fighting in same nation so that they carry maximum troops. - Do not wait and watch the battle and be ready for the next attack (after the wait timer).
- You can send the other heroes on wall or on an attack so that they do not irritate you in the selection process and you can always choose the designated heroes from the list just from the top 4. This will fasten your process of attacking.
- With these tricks, which are obvious for a veteran player though, you can make maximum damage loosing lesser troops. You can claim better prizes, for example, a military bonus buff everyday is good enough.
