I'd like to change the damage amount done to the player and potentially add blood drops as well. In the pack I'm working on I start the players out with only 3 hearts so it would be really nice to lower self-damage a bit for the early game.

The problem I'm having is that the sample document doesn't include me and I can't click on myself with the dev knife; that just reloads the scripts.

ah... That got overlooked when I had made the configs, I'll see about adding support for that soon.

Support for that has been added in v5.5.0, you can use "player" as the entityID and set the min/max damage like normal. Only different is that you can't set customs drops for the player.
