Describe the solution you'd like
A message (sent to chat) when the perk successfully fires.

Why is this feature needed
When creating "crit chance" style damage boosts or random loot rewards—it'd be nice to let the player know that.

Describe alternatives you've considered
Getting a cat.

Additional context

example of configuration and ingame message

leaving this as a note to myself. A perk property to notify on chance would allow the perk to supply a message without making it apply to all perks.
