I suppose it's still plenty thematic to start winding at 1. (or treat 1 as ).
If 2
is worth an increase of 2 then I'll go with 1:time being worth an increase of one. They both can end up the same, but multiple uses is
more equally thematic,
which i'm inclined to go with.Or, if it's better to have a higher cost for higher DR, it could be X: Increase DR by 1, Where X is the current DR. Thus maintaining DR 4 would be Casting Cost +
+
+
+
Onward, in other words, Casting Cost + 6
+ 3
per turn to get to and maintain 4 DR. While maintaining 3 DR would be Casting Cost + 3
+ 2
per turn
