Module:LevelStats

Displays a stat table for units for multiple levels. Parameter names are the stat abbreviations, for the first level just the two letters, for the 10th level the stat abbreviation with suffix 10, e.g. dm=5 for damage 5 in level 1 and dm10=20 for damage 20 in level 10. Values are interpreted linerarly for the other levels.

For units use exp=true for exponential stat growth.

To display a gain indicator, use gainIndicator=true.
