A test showed that a 500 Dodge stat resulted in a 50 % dodge chance.

Basic shields have a dodge bonus of 2.
That means a chance of  0.2 % (!)  to dodge/deflect an attack.      That has to be a very very small shield.

Spell descriptions also point at a decimal error.

Cloak of Shadows:   "Increases the caster's dodge chance by (15) for 4 rounds."
  Spell effect:    increase dodge stat by 15.

So for 10 mana you increase a unit's chance to dodge by a whopping 1.5 %... for 4 rounds.  Yay.

Quite obviously someone changed the Dodge Maximum (why, if it's a float?)  from the intended  100 to 1000  but forgot to tell the content team who created the items and spells.
