Ahoy!
I'm not home right now, but a major thing needs to be clarified here.
The ally and enemy scopes are treated in an entirely different way. If you want to damage someone, be it an ally or enemy, you must use the enemy scopes.
If you want to damage enemies and allies alike, you must use the All Enemies scope, you must activate the self-damage effect with the note-tag, and even this way, only targets within range will be damaged. So, if you want to damage everyone on screen, you will need to increase the tool size too.
Also, to enable the tools with my bugfixes script, just turn on the switch you set up in the script, and it should work.
Will re-read the topic tomorrow, when I get home, in case I missed something here.
