The mortar has the function of destroy the enemy by missile that upon impact with the ground of the village produces splash damage, i.e., what damages or destroys everything around it.
Has a range of 4 tables and can not attack air units but can produce enough damage to groups Arques, Barbarians, Elves and magicians.
The trouble with the mortar is its trip time becomes much and that if a troop is directly attacking what it can do nothing to fight back because you have a small room where you can not launch their missiles. This margin we see when we click on them and you see a red circle around.
Really slow in improved so we have to keep in mind that we can not use to defend. They do not have much life can be destroyed so easily.
How do I place? Typically place giving protection to each other or covering the maximum of the village. When we 2 just be sure that your injury margin coincide with each other and having 3 place them in a triangular shape within the village. Mortar now have other more, so I recommend using the diamond shape within the village. Important place in the village centered mortars, outside it are not very useful.
We have various types of mortars as we go the better:

This is the basic level mortar, we found it to improve the municipality level 3.

Mortar level 2 is achieved by raising the municipality level 4. Change in appearance with 2 golden gears for each side and gold trim on its way out.

Level mortar 3 is a clone of level 1 except that it is slightly wider and has gold trim.

Here we see again the side gears and has a rich golden color. Now has 2 rings over the golden gun.

Mortar level 5 is wider and has a larger projectile. Just one gear on each side and has a wide gold trim.

Mortar level 6 is almost entirely gilded, has three side gears. Is of the same dimensions as the mortar level 5.

In the mortar level 7 note that it is not as golden as above and having skeletal remains around. The muzzle becomes silvery.

Mortar level 8 It is the largest of its kind. It is dark silver color with golden spikes. Inside seen a reddish color as if it were full of lava.

And we have available to a new level of mortar level 9. It is much more golden than its predecessors and incorporates a golden chain. The dark gray color disappears giving way to a more silvery color,.
To access this level need to gather 9.000.000 gold and we have to wait 12 days until you can have it once set to improve.
We have a New Update October 2016 where we talk about the new level 10. Coming soon will post pictures of this new level and talk about it.
Mortars are important in defending our castle, normally troops and these are grouped with their shells produce an expansive damage to these troops.
Here I leave the Table scheme improvements mortars:
| LEVEL | DAMAGES FOR SECOND | FIRE DAMAGE | LIFETIME | COST OF GOLD | TIME FOR IMPROVEMENT | EXPERIENCE | LEVEL OF HALL |
|---|---|---|---|---|---|---|---|
| 1 | 4 | 20 | 400 | 8.000 | 8 hours | 169 | 3 |
| 2 | 5 | 25 | 450 | 32.000 | 12 hours | 207 | 4 |

Hope you like big help.
Hola William andres , Any defense that is improving cannot defend since it is under construction...he,I,I, however in the war village you will still defend at the previous level of improvement. When we start manufacturing a new defense that we did not previously have, This can be used in the War village even if its creation has not been completed.. A greeting and thanks for comment. Thanks for commenting and greetings. guíaCOC team.
Hello Write Wizard, what you say is true, a mortar.,canon,
or any other defense does not attack when it is improving
Hola, giovannidelic , concerning him that defends your mortar can not be due to several causes:
1. You're improving it and then not defend until improvement is completed.
2. Not covering the area of action of the mortar, i.e., when you click on the mortar it will mark an area of action which he defends, if the enemy troops do not enter that area will not defend. Also, if you see how much the mortar has a small area marked in red action where not defend itself if the enemy troops enter it.
If after these tips remain mortar test run you uninstall the game and reinstall habiéndote previously discharged from Google play or Game center.
A greeting.
