Easy defeat of Allora
When you are on Hoth at the room before you get to Allora, you will see a Wampa attacking a Tauntaun. Save the Tauntaun from dying and ride it into the room with Allora. When the battle starts, immediately ram the Tauntaun into Allora (by right clicking). It will be an instant kill.
Defeating Reborns
Activate Force Speed (works best with grade 3 speed) and slash once at their front to lure them down. Then, run around behind them and slash their back as many times as possible. This works best if you push them in a corner and complete the procedure.
Use the following trick to kill Reborns, Reborn Masters, Jedi, and other Force users. Use Force Grip to hold them in the air, then throw your lightsaber at them to kill them. It is harder to do to some, but if you timed correctly you will hit them. This usually works best with Grip level 3 and Saber Throw level 3, but is still possible to do with the other levels.
When fighting the Reborns at the start of Chandrilla (after the bridge is blown up), lure them all to the bridge then jump over to the other side. Two of the Reborns will attempt to jump over as well, but will fall to their doom.
Defeating Sand Worms
Notice that there are a lot of thermal detonators on the sand worm level "t1_danger" (merchant rescue mission). You can kill the sand creatures with them. throw them somewhere away from other objects in the map (because the Sand Worms do not go where the rocks and other things are found). With about two of the thermal detonators you can kill the Sand Worms, providing they eat them. However they do not go away permanently, even if you kill all of them. Some can still respawn. Also, if you stand still on the sand in the level, the Sand Worms will not eat you (the NPCs are programmed so that they only sense your player or anything else when it moves).
Defeating Wampas
To kill a Wampa quickly, let it grab you. As you are hanging upside down, swing your lightsaber to cut off its arm and kill it instantly.
