1. Your summonings must be an animal or beast of some kind.
   
2. Please avoid making elemental summonings
   
3. You may only have 1 summoning contract
   
4. For each summoning contract you can only have nine summonings coming from that contract
   
5. Your boss summon must be near the power of Gamabunta or a little above anything stronger is to much
   
6. A summoning may only use one element
   
7. Once a summoning uses all of it's chakra it will disappear
   
8. A summoning can be killed
   
9. The max amount of jutsu a summoning can have is seven jutsu
   
10. All summoning contracts must have a kid level summon
    
11. You don't start off being able to summon the boss summon
    
12. You may only have a maximum of two elder summons in your summoning contract
    

Chakra and jutsu for summonings:

Elder summon have 85 chakra; can use six jutsu E-S

Boss summons have 100 chakra; can use seven jutsu E-S

Grown up level summons have 75 chakra; can use five jutsu E-A

Adolescent level summons have 40 chakra; can use three jutsu E-B

Kid level summons have 10 chakra; can use one jutsu E-C

Summoning types:

combat summons:these summons are used for combat they mostly use offensive and defensive jutsu, these summons

communication/tracking type:these summons are used to send meassages to others or track a person.

transportation type:These summonings ar made for transpoting people to another area these summonings have the greatest speed out of all the types of summons

For each type of summon you can only have a certain amount. Also during battle you can only summon one at a time.

Combat types: 4 total
Communication/Tracking: 2
Transportation: 2

Also only Jounin level and Higher can summon a Boss summoning

Chuunin can only summon and have full control over adolescent summons and under.They are able to summon one grow up summon but the summon might not listen to the summoners commands resulting in a waste of chakra.

Another thing is that only Chuunin and higher will actually be able to use the summoning jutsu.
