 if you have two abilities `do` and `do1`, the command `/do1` will trigger the `do1` ability. 
 ## Statistics
 AbilityBot can accrue basic statistics about the usage of your abilities and replies. Simply `enableStats()` on an Ability builder or `enableStats(<name>)` on replies to activate this feature. Once activated, you may call `/stats` and the bot will print a basic list of statistics. At the moment, AbilityBot only tracks hits. In the future, this will be enhanced to track more stats.
