Pets

Pets can be found in the Cabal Cash Shop (Coins icon in the bottom right of the screen) or can be brought from other players however they CANNOT be found as drop in the game worlds.

Similar to other items pets have slots which can hold different "perks" however, unlike Equipment they do not have a maxium of 3. (you will never see a triple slot unless you own it)
Pets can have up to 10 slots, also unlike equipment you cannot use catalysts when trying to get a slot filler it is purely luck however, in the filling proccess there are believed to be "better" slots in which to put your cores.

Example: My Peng (lvl 6)



Abilities:

Sword Amp Magic Amp Crit Dam
Crit Rate    
     
Resist Stun Resist Crit Rate Resist Crit Dam
Resist Unmove    
     
HP MP HP Auto Heal
MP Auto Heal    
     
Defence Def Rate Attack
Attack Rate Magic Attack Add Damage
     
Alz Drop + (amount)    

To be able to Give your pet slot fillers you have to take it to a Core Alchemist along with a Force Core Highest (FCHH), Once there depending on your pets level the upgrade will cost...

Level 1 to 4 1,000,000 Alz
Level 5 & 6 2,000,000 Alz
Level 7 & 8 3,000,000 Alz
Level 9 & 10 5,000,000 Alz

(correct me on the forum if infomation is incorrect)

Apart from having slots to be filled pets have no real use and pets which cost more (Peng / Wooly / Rudolf / Etc) are not better than cheaper pets (Mummy / Garlie / Rabbithorn)
