| Assuming you've built your character in the conventional Conular/Lord way, with a lot of CHA and WIS and very little STR or DEX, I wouldn't worry about things like bonuses to hitting and defence as by the middle of the game you'll be too pun y to hit anything anyway! Nor would I worry too much about skill-boosting items, unless getting XP from doors and mines was a priority to you. Skills let you make stuff, but the vast majority of that stuff increases your ability to hit things or allows you to upgrade armour; neither is of concern to you.
Obviously, you want to wear something that doesn't interfere with the use of Force Powers, since as a Lord you'll be mostly relying on the damaging ones like Lightning which aren't usable with armour. I'd go for the Jal Shey armour myslef, usually with a biores inlay. I don't like to wear brown 'Jedi' robes when I'm playing Sith, it offends my sense of canon, so I avoid the Ossus Keeper robes.
My lightsaber I construct as a boosting device, rather than a hitting-people device. I install a deflecting emitter and ossus duelling lens and take deflection as a power so that blaster bolts don't hit me too much; I install the 'MyName' crystal for the CHA boost and in the other slot I put a Ruusan crystal (+1 each WIS and CHA)...or a Kaiburr crystal if I'm lucky enough to find one (about 1 game in 20)
I usually take a high level of CON so I can use a good implant which boosts CHA and WIS, usually a mental Boost D package, I wear the best WIS boosting headgear going. There aren't any belts which really help, so I'd go with an Immunity/Immortality to reduce damage when people do manage to hit me before I Lightning them into oblivion. Jal Shey gloves, obviously.
With this lot and a WIS of base 18, You should be able to kill most non-bosses in a singel Force Attack towards the end of the game.  |
