[provocating]

Just trying to help narrow it down, looks like it refers to this block of code right ?

// Ok now, let's check pet's offhand. 
					if (attack_dw_timer.Check() && GetOwnerID() && ( GetOwner()->GetClass() == MAGICIAN || GetOwner()->GetClass() == NECROMANCER || GetOwner()->GetClass() == SHADOWKNIGHT || GetOwner()->GetClass() == BEASTLORD ) ) 
					{
						if(GetOwner()->GetLevel() >= 24)
						{
							float DualWieldProbability = (GetSkill(DUAL_WIELD) + GetLevel()) / 400.0f;
                            DualWieldProbability -= MakeRandomFloat(0, 1);
							if(DualWieldProbability < 0){
                                Attack(target, 14);
                                if (CanThisClassDoubleAttack())
                                {
                                    sint32 RandRoll = rand()%100;
                                    if (RandRoll < (GetLevel() + 20))
                                    {
                                        Attack(target, 14);
                                    }
                                }
							}
						}
					}

And something about the pets duel wield ? Well as far as pet classes that bit of code looks for he had MageX2, SKx2 and BLx1, Necx1

He does not give them weapons or gear.
