Adds the specified amount to the player's life, scaled by the player's defense multiplier if necessary.

Required parameters:

- value = add_amt (int)
  Specifies amount of life to add to the player's life bar.

Optional parameters:

- kill = kill_flag (int)
  If kill_flag is 0, then the addition will not take the player below 1 life point. Defaults to 1.
- absolute = abs_flag (int)
  If abs_flag is 1, then exactly add_amt is added to the player's life (the defense multiplier is ignored). Defaults to 0.

Example:

`none`
