How can i prevent these out of range exceptions, "System.IndexOutOfRangeException: Index was outside the bounds of the array"?

Question

First of all, TamerData is attached to a new byte array as you will see stated in the function, within the lobby class. Now the troubling area is that in the error log it shows that line 260 is incorrect, which is "qry.Add("maxHP", TamerData[charModel - 80001][3]);". Now TamerData is a byte array as i've said. Another error that is being recieved is, "CreateChar Ikuto Frosty Error: CreateCharacter()" <--- Main error being dealt with. This function is shown in the source code.

Line of Error

qry.Add("maxHP", TamerData[charModel - 80001][3]);

--Database-lobby.cs

public static byte[][] TamerData = new byte[][] { new byte[] { 10, 2, 90, 80 }, new byte[] { 8, 1, 100, 90 }, new byte[] { 8, 1, 90, 100 } };

public static int CreateCharacter(uint AcctId, int pos, int charModel, string charName, int digiModel)
        {
            int charId = -1;
            try
            {
                using (MySqlConnection con = Connect())
                {
                    Query qry = new Query(Query.QueryMode.INSERT, "chars");
                    qry.Add("charName", charName);
                    qry.Add("charModel", charModel);
                    qry.Add("accountId", AcctId);

                    qry.Add("inventory", new ItemList(63).Serialize());
                    qry.Add("storage", new ItemList(70).Serialize());
                    qry.Add("equipment", new ItemList(27).Serialize());
                    qry.Add("quests", new QuestList().Serialize());

                    qry.Add("maxHP", TamerData[charModel - 80001][3]);
                    qry.Add("maxDS", TamerData[charModel - 80001][2]);
                    qry.Add("HP", TamerData[charModel - 80001][1]);
                    qry.Add("DS", TamerData[charModel - 80001][2]);
                    qry.Add("AT", TamerData[charModel - 80001][0]);
                    qry.Add("DE", TamerData[charModel - 80001][1]);

                    using (MySqlCommand cmd = qry.GetCommand(con))
                    {
                        cmd.ExecuteNonQuery();
                    }

Thank you for any help that is given, sorry if my question isnt very specific or relevant to any other user, this has just been very troubling.
