How to find out the hero's armor

I'd like to make a spell that gives bonus damage based on how much armor my hero has at the time. But I can't find a way to get that information. I could probably compute it from the hero agi, item and buffs, but it seems to me like it's gonna be complex, require a lot of ressources and be very hard to keep updated since every new item or skill will have to be known to the algorythme.

Please tell me there is a function that return current hero's armor :)

P.S. I'll probably be using other stats too like attack type, armor type, etc. so if there is a set of function to find out those too, it's going to save me another question later :)

You can try searching for stuff in future. Attack type and armour type cannot be determined by a function.

I stand corrected, I looked all over the Jass Manual and did'nt find any :S

Note to self; Must not forget to search the forum first

Edit: I need to learn how to read.
