Break chances are WP%
- If weapon breaks : set Attacker current action special flag to 0x10
- If weapon do not break : set attacker special flag to 0x08
Notes : -Skip the routine if attacker is a mime ( hard coded mechanics )
-Special flag 1 0x08 and special flag 2 0x10 overrides every other specials flags (1 and 2) in Draw_out_routine_dealing_with_experience_gain - called after the end of preformula routine
-Breaking a katana leads to special flag 1 0x10 (steal item) - but in Draw_out_routine_dealing_with_experience_gain it's special flag 2 0x10 which is checked (bug?)
