[Spell] Increasing Spell Damage with Items.

[Kedaze]

Hello guys,I'm making a map that have some items that gives all my heroes Increased spell power.(Just Like WoW)
But I was reading some stuff that I have to make a trigger for it since wc3 doesn't have any ability that does that,so my question is:
What I have to do to make all my spell do more damage with certain items?

Thanks in advance.

(Sorry about my English)
