hmm.... possible solution, Under equipment, buy your dagger as a str-based dmg 2 effect for 2 equipment points, then buy light leather armor(Protection 1) for 1 equipment point.
With your str of 1, the dagger dmg is still 3.
or possibly just check your calculations of the defenses.
STR:1 STA:0 AGL:4 DEX:3 FGT:2 INT:2 AWE:1 PRS:0
Ddg:7 Par:6 Frt:5 Tgh:5/1 Wil:5
Dodge 4Agi+3points = 7
Parry 2Fighting+ 5points = 7
Fort 0Stamina+5points = 5
Will 1Awareness +4 points = 5
is... 17 points spent on it
Take the two, spend for a point on Stamina and you get your Fort up to caps ,
With the point of stamina and the leather armor from above, you can get to Toughness 5/2 (1sta+1armor+3def.roll), you can drop a defensive roll and bring your Will back to 6 to meet caps.
Just a thought.
