=== Summary ===
 Check Attacker ID (<0x15 and not 0x00ff) - If not OK Exit with r2 = -0x01
 
 1st Skillset Action menu
     - For Default and monster - check the [weapon range] flag of the ability
  
 2nd Skillset Action menu check : 
     - Attack, Charge or Default + [weapon range] or monster + [weapon range] 
              - Choose right or left hand weapon 
              - 0x00 if Monster or frog
              - Right weapon ID if exists else left. (Not a shield checked)
              - Load Item secondary data attack type (arcing, direct and lunging will have specific routines)
     - Else 
              - Force Attack to a direct flag
              - If Attacker 0x178 = 0x06 (Target-Specific Ability?)
                     - Check Target ID validity - if not OK, exit with r2 = -0x01
                     - Update Target Coord on stack 0x24 0x28 and 0x26 (not found for which purpose)                          
 
 Weapon attack type check
     - Arcing weapon : set trajectory and update target if obstacle
     - Direct trajectory : not investigated, return a Target ID (might check obstacle)
     - Lunging :  - check if Target is close to attacker 
                          if not : routine not investigated, return a Target ID (might check obstacle)
     - Else check Attacker and target delta height	: Target invalided if difference is too high
 
 Disable all tiles green flag (Tile 0x05 byte, flag 0x80)
 If target ID is valid : enable green flag of target tile
