Reducing Melee/Normal & Ranged/Pierce Damage by %

[Panik]

The idea is to make powerful items also useable to low-level heros without overpowering them. Instead of of reducing incoming damage by a flat value I want to reduce the damage by a percentage. The idea was to make use of the Mountain Giant's ability to reduce melee damage with armor and ranged damage with shields. I have a working Item System (Click if you care) and working spellbooks, but the problem is that I can't find a way to reduce the damage by a percentage. So I tried to reduce damage types, which allowed me also to reduce magical damage. Pierce damage seems to be reduceable with the ability of the Nightelf Archers (didn't test it yet), but I can't find a way to reduce normal damage.
To make it short: I'm searching a way reduce incoming normal (or melee and ranged) damage by a percentage without using a damage detection system, for that would mean to check for every possible equipped item.

With defend-like abilities you can reduce only magic and piercing damage, if that is what you wanted to know

Elune's Grace does what you want. Specific-damage type is a way I do not suggest following, since every type of damage is not included within the default abilities. Reduced damage taken of type Spells/Magic can be done, by adding the Spell Damage Reduction ability.
