+If the award is counted, ie: there's a trigger.target property, then the difficulty
+multipler is timesd by target to get the overal difficulty. If the award isn't a
+counted type then the difficulty multiplier is used as the overal difficulty.
+Award difficulty affects how awards are sorted in a list - more difficult awards
+are further down the list.
+
+Actual code used to calculate award difficulty:
+
+```lua
+local difficulty = def.difficulty or 1
+if def.trigger and def.trigger.target then
+	difficulty = difficulty * def.trigger.target
+end
+```
