The basic idea is to use hero skills as the gauge to value most properties of items in terms of runes spent in order to obtain the same effect from a skill (or multiple skills).

The list of properties in terms of rune value (corresponding skills in parenthesis)

rage : 36 = 24 rage -> 1.5 runes/rage (rage control)
attack/defense = 32/6 attack, 27/5defense, 33/3attack+3defense -> 5.5 runes/attack or defense
(heroism, resistance & the power of spirit)
% critical : 36 = 10% -> 3.6 runes/% critical (prayer)
---- side note: 1 attack/defense = 1.53% crit, equivalent to the case of |attack - defense| = 35
% experience : 39 = %20 -> 2 runes/% (learning)
% cash : 18 = 30% -> 0.6 rune/% (trophies)
intellect : 5 runes/int (linguistics)
mana : 1.5 runes/mana (absolute balance - rage)
scrolls : 30 = 18 mana + 9 scrolls -> 0.33 rune/ scroll (wisdom - mana)
% restore mana : 27 = 100% + 12 mana = 100% + 18 -> 0.09 rune/% (meditation - mana)
attacking spell power: 36 = 50% -> 0.72/% (destroyer)
mana/turn : 9 runes = 2 mana/turn -> 4.5 runes/(mana/turn) (concentration)
extra magic : 42 / 6 extras = 7 runes/extra magic(higher magic)
% damage: suppose |attack - defense| = 20, +1 attack = + 3.33%/(1.67) = +2% damage -> 2.75 runes/% damage
% all resistance : use divine armor (without int modifier)
---- 35% = lvl3 order + 30 mana/4turn + 2 extra magic in first 10 turns + lvl3 magic light
---- 30% = 38 + 33.75 + 14 -> 2.86 runes/%
or 35% = 38 + 33.75 + 14 + 27 -> 3.22 runes/%
---- ~= 3 runes/% all resist
initiative : use battle cry
---- 3 initiative = lvl3 order + 15 mana/3turn + 3 extra magic in first 10 turns
---- 3 = 38 + 22.5 + 21 -> 27 runes/initiative
speed : use lvl3 haste
---- +2 speed = lvl3 distortion + 10 mana/4 turn + 2 extra magic in first 10 turns
---- 2 speed = 39 + 11.25 + 14 -> 32 runes/speed
% physical resistance : use stone skin
---- 40% - 1 initiative = lvl3 distortion + 7 mana/5turn + 2 extra magic in first 10 turns
---- 40% = 27(initiative) + 39 + 6.3 + 14 -> 2.2 runes/%
% fire/poison/magic/astral resistance
---- = (% all - % physical)/4 = 0.2 runes/% (reasonable since they are specific while physical is universal)
morale : suppose troop = 20 attack/defense 10% crit
---- 1 morale= 2 attack + 2 defense + 2% crit = 22 + 7.2 = 30 runes/morale
+ % leadership : suppose |attack - defense| = 0, 1 attack + 1 defense = 3.33% more damage + 3.33% less loss = 3.33% more troops, thus +1% leadership = 1/3 attack + 1/3 defense = 3.67 runes/%
+ leadership : suppose 30k leadership in the end, +1000 leadership = +3.33% leadership = 11 runes
