So, I am also very much a novice when it comes to custom deeds.
I assume you've found them in Preferences
, so you've seen the big help
button on the right.
Since the event isn't an item or a skill it's probably best as a command.
In the Builder (the thing that comes up when you press "add custom") ...
1: select - Command
(on the left)
2: Add display text (StarGaze)
3: add the preference (I have no idea what preference tracks uses of this)
4: add a gCLI command to do it (probably adv *Location*)
5: if it can be used 6 times, make this 6...
6: add a toolTip ("Click here to StarGaze")
7: add a completion Message ("Stars, man. How do they work?")
Save it. Then make with the clicking!
