The intention of this character was to race to the dual-scimitars of death (i.e. imp.2wf + maximum critical threat + devastating critical), while actually being a strong all-around character in the low and medium levels. The goal is achieved at level 25. The two main weaknesses of this character are the low HP (for a fighter) and the Will save, but IMO it's a fair trade.
Skills maxed on rogue levels are Tumble, Traps, Locks & Search. Skills maxed on Fighter/WM levels are Discipline, Heal and Lore to level 9, then just Discipline afterward.
All ability upgrades go to Strength.
This character can use whatever weapons s/he likes until specialization at level 12.

After level 25 you can do what you like: 4 more fighter levels would give epic weapon specialization, HP could be improved with Toughness... you know the drill.
