+28 hp?
or 5% NORMAL DR, +2 dmg threshold?
IMO, second lifegiver might be better. Toughness wouldn't apply to damage from rocket launchers, energy weapons, flamethrowers which are all heavily used in the game.
And what about dodger? Think it's worth it? Would 5 more AC help evade more bullets from burst?
Keep in mind 5 AC is a big number because most armor will have 15-25 AC.
