Shield Booster + Deflector Regeneration means it doesn't matter what Shield you use.
Charge Weapon means it doesn't matter what weapon you use.
Max Intelligence (Special abilities) and Will (Lust defense) and put your leftover points in Physique.
Grab the Light Jetpack on Uveto and you can hit flying enemies with melee attacks.
Gravidic Disruptor is for anything with a high resistance to Electricity. Thermal Disruptor does more damage, but Gravidic is unresistable.
At level 10 you regenerate 20 Shields/round if you don't take Shield damage. Paralyze enemies when your Shields get low, and/or get a Stun Chance weapon* for a 1/5 chance to regain 40 Shields with every hit.

Custom Shock Gear. Custom Shock Gear is the best, but Sparring with Shizuya can be annoying.
Your one weakness is enemies who can do damage through Shields. The most annoying is the Corona Lord Flamer. Get a Salamander Longcoat from Myrellion, buy some Field Surgeon's Kits or Doctor's Bags from Bianca. Or just rest for awhile when your HP gets low.
