At Level 30, I can reach a value of 71 in Defense.
Character:
- Starting Attributes:
- Strength (STR): 10
- Dexterity (DEX): 16
- Then increase every fourth level, yielding 7 increases at Level 30
- Constitution (CON): 15
- Intelligence (INT): 8
- Wisdom (WIS): 16
- Charisma (CHA): 8
- Light-Sided: Better Name Crystal
- Classes
- Male: To gain the Battle Precognition Power from the Handmaiden, which adds your Wisdom Modifier to Defense.
- Feats
- Equipment
- Implant: Quickness D-Package (+4 DEX, +1 Defense2)
- Head: Circlet of Saresh (+5 WIS)
- The Target Assessor is a nice alternative for characters without Battle Precognition or for those who want to sacrifice a bit of Defense for a bit of Attack (+2 DEX, +2 Attack)
- Hands: Improved Automation Gloves (+5 DEX)
- Armband: Vao Armband (+1 DEX)
- Belt: Aratech Echo Belt (+4 DEX)
- Robes: Ossus Keeper Robe (+4 WIS, +1 Defense2)
- Lightsaber: Only a single Saber1, and only the Name Crystal matters, because the game only takes the highest of multiple modifiers for the same Attribute. (+5 DEX, +6 WIS)
- Assume the Name Crystal at Level 30
- Even though for playing purposes, this is probably not a realistic scenario because you can't upgrade the Crystal once you have found all of the Jedi.
- Why not throw a Fencing Emitter (+2 Defense) in there anyway, to offset any Defense penalties2? In any case, I think it's the best emitter for offensive characters as well.
- Active Force Powers
Calculation:
- Base: 10
- Class: 14
- Dexterity: 18 (from the modifier for 47 DEX)
- Wisdom: 16 (from the modifier for 42 WIS)
- Dueling: 3
- Powers and Effects: 102
Notes:
1: Initially, you would assume Dueling would provide the highest bonus, since it grants +3 to Defense with Master Dueling. But then, you realize that Lightsaber upgrades can provide Defense bonuses, and that a Fencing Emitter and a Lorridan Gemstone together will result in a Defense bonus of +4. But, then you realize the game caps Defense bonuses from Items and Effects at 102, and you can reach that with Force Powers alone. And Lightsaber Crystals do not provide sufficient bonuses to Wisdom or Dexterity to overcome the +3 from Dueling. So, Dueling does indeed provide the highest ceiling for Defense.
2: I could only see the cap of 10 Defense from Items and Effects in-game, but it seemed to accord with the rules from KotOR. However, any bonuses in excess of 10 can offset any penalties from Attack types like Critical Strike (-5 to Defense) or detriments from Effects like Slow.
3: You can actually achieve four +1 CON bonuses, but instead of the fourth, you can gain a +2 WIS bonus instead, which has more value for the pure-Defense character.
