I've read all the pet system suggestion,,,,,
one that I read is a lot complicated and to many memory to waste...

here's my idea....

I see a spherical bird, and I know that you have seen it a lot.....
this will be the pet.....

first, the appearance of the pet....
=> you will be able to chose the color of your pet *just like in the creation of the night
=> you will be able to chose the size of your pet *the size will be smaller to bigger
=> you will be able to give your pet a name

second, the skill....
It will be inborn to the pet.
In the creation of your pet you will chose one skill.

*Each skill will required a pet level.

here's the skill:
I'll just use the implemented abilities in the game.
Each pet skill will give a less boost than the Unique Variants Abilities of a Weapon and Equipment.
As your pet level up, it will add an additional skill in with a specific abilities

Aggressive Pet => this pet will boost your damage.

examples :
Level 1 => Damage Bonus vs Beast Family
Level 2 => Damage Bonus vs Construct Family
Level 3 => Damage Bonus vs Fiend Family
Level 4 => Damage Bonus vs Gremlin Family
Level 5 => Damage Bonus vs Slime Family
Level 6 => Damage Bonus vs Undead Family
Level 7 => Damage Bonus vs Swarm Family
Level 8 => Damage Bonus vs Spiral Knights *This one is for PVP.
Level 9 => Increase Damage Bonus Percentage vs all Families and Spiral Knights

Haste Pet => this pet will increase your attack speed and movement speed.

example:
Level 1 => Increase once movement speed *This can be applied in Clock Works or in PVP arena.
Level 2 => Increase attack speed using a sword
Level 3 => Increase attack speed using a gun
Level 4 => Reduce Charge time using Bomb
Level 5 => Reduce Charge time using Sword
Level 6 => Reduce Charge time using Gun
Level 7 => Increase percentage of once movement speed
Level 8 => Increase percentage of attack speed for all weapon
Level 9 => Increase percentage of reduce charge time for all weapon

Aegis Pet => this pet will increase your damage resistance and status resistance

example:
Level 1 => Increase once damage resistance *For monsters
Level 2 => Increase Damage resistance for Curse
Level 3 => Increase Damage resistance for Fire
Level 4 => Increase Damage resistance for Freeze
Level 5 => Increase Damage resistance for Poison
Level 6 => Increase Damage resistance for Shock
Level 7 => Increase Damage resistance for Sleep
Level 8 => Increase Damage resistance for Stun
Level 9 => Increase once Damage resistance *For PVP

Third, Acquiring pet
I don't have any idea how to acquire the pet......
I'm thinking that it will be acquire by the mean of a quest or bought it on a pet vendor.
Since a pet is a special item, it can only bought using energy......

What d you think about my idea of a pet system???
