 Description
 ----------- 
 The sonic screwdriver comes from the planet Gallifrey, in the constellation
 of Kasterborus, in a galaxy far, far away. Not only can it unscrew and unlock 
 things, it also has its uses as a weapon, particularly against machines. 
 Damage Bonus, Sonic +2
 Damage Bonus vs. Droids, Ion +1-4
 Repair +2 
 To get it in-game, it can be purchased from Crattis Yurkal on Dantooine. 
 Alternatively, you can get it by typing "giveitem di_ssd_01" 
 and "giveitem di_ssd_02" into the console, without quote, 
 and hitting the return key. :) 
 This mod adds two items to the game: a weapon, the stats of which are 
 outlined above, and a useable item. The useable item will allow the player
 to open closed doors and unlock placeable items, dependent on scoring 15 or
 higher on a random number generator out of 20. If not, the effect will fizzle.
 The player also needs to have the sonic screwdriver weapon actually equipped
 at the time in order to use this. 
 N.B.: This mod is incompatible with any other which modifies the file
 "dan13_crattis.dlg".
