Describe the solution you'd like
The level of the current skill be added into commands to expand their features.

%level%: command = "say @s just gained level %level% in Agility!"

Why is this feature needed
Would allow for completely converting fireworks over to chat commands.

Describe alternatives you've considered
Wallowing in a pit of despair.

Additional context
Perhaps have a way for the commands to be run without being bound to a player, then such messages could be server broadcasts rather than from a specific player. Would probably want to add %player_name% as well with this, though, so they can still be named (and shamed).

pmmo already lets you store player skills as a scoreboard value. via /pmmo store you can use that inconjunction with this to create a function that achieves this behavior.
