Darth Nihilus (I think his name was) was easy. Darth Sion was easy. Darth Treya was easy.
No, I take it back. My character was too powerful.
At the end of the game, at my final save, this is my character:
Jedi Sentinel 15 / Jedi Watchman 11
Str 16, Dex 29, Con 18, Int 19, Wis 31, Cha 18
Vitality 363, Force 511, Defense 46
Fort 20, Ref 26, Will 25
And here are my two lightsabers:
Violet (Total Damage, after modifiers, 21-58 and total attack bonus +36)
Damage 12-40 energy, +3 light side, +1-10 cold
Attack +2
Defense +2
Dex +3, Str +3, Wis +4, Cha +2
25% to Stun for 6 seconds at DC14
Cyan (Total damage, after modifers, 16-53 and total attack bonus +36)
Damage 12-40 energy, +1-10 cold
Attack +2
Defense +2
Cha +2
Wis +2
And my other equipment:
Ossus Keeper Robe (Def +1, Cha +2, Int +4, Wis +4, Con +3, Regeneration +3)
Circlet of Saresh (Wis +5)
Marcus Artorius's Armband (Con +1)
Jal Shey Meditation Gloves (Dex +2, Wis +2)
Alacrity Implant (Ref +1, Dex +2)
Tech Specialist Belt (Dex +2, Str +1)
Significant Powers and Feats:
Force Enlightenment, Stasis Field, Force Storm, Force Wave
Master Two-Weapon Fighting, Master Flurry, Lightsaber Specialization/Finesse, Improved Toughness, Regenerate Force Points and Vitality
Then after finishing the game, I thought to myself, "Is there any logical reason to use a double sided lightsaber or a single lightsaber instead of two regular sized lightsabers?" The dueling feat gives you a +3 to to defense while my two lightsabers, together, gave me +8 (including Dex and Wis modifers). If I used my best lightsaber and the dueling feat, I'd have the same defense but would do a lot less damage.
My character was groovy. Too bad the end wasn't more difficult.
