I like it, but I also believe that the damage reduction should varies from 0 to 3 (average=1.5) unupped and 0 to 5 (average=2.5) upped, even if that means reducing the cost by 1 or 2
quanta in both upped & unupped versions. Entropy shouldn't have a DR shield with an average of 3 unupped (same as Earth's upped Titanium shield). Don't forget that there is a thematic reason
has the biggest vanilla DR shield around and other elements shouldn't be able to have shields as powerful as Titanium|Diamond Shield.
