Attribute Bonus

Hi ! I'm currently working on a map and I have to do the attributes and their bonuses . Some attributes would be :
--From Warcraft III :
*Strength
*Agility
*Intelligence
These are classic. Now the custom ones :
*Endurance (Increases your Hp by x per point )
*Spirit (Increases your Mp by y per point)
For both I'll use blade.dk's Set unit's max state System.
The harder ones :
*Charisma (Increases the attack and defense pets - some summoned units )
*Stamina (Increases the Hp of ur pets - some summoned units)

Now i wanna know some ideas about making the bonuses for : Charisma and Stamina . I accept any ideas . And if someone can tell me about a type of shield that absorbs damage and i can detect its life / max life , it can be destroyed with triggers ...I really need this so Please tell me . Thank you !

Attack - Attack bonus tome. Stamina - use the functions for setting max HP/mana. I see no problem there.

Defense will need to use BonusMod. Earth-Fury submitted a very neat implementation of that using NewGen to the Hiveworkshop's JASS section.

Sorry - Attack bonus tome ?
wow I didn't know about Earth-Fury's Bonus Mod and thx to NewGen Editor hack i can copy the abilities with the same raw code .This is also good for attack . Thanks Captain Griffen ! (those were only some of my ideas and I have more but its enough for now)
