Here is the table (for 5.x) for the number of blows for a given strength and dexterity. If your strength or dexterity is 18+xx, that is stored as 18/xx; thus, for example, you need an 18/90 strength to use the bottom row of the table with a katana (12 pounds). If you don't know the weight of a weapon, set the option "Show weights in inventory." /* used to calculate the number of blows the player gets in combat */ int8u blows_table[7][6] = { /* STR/W: 9 18 67 107 117 118 : DEX */ /* <2 */ { 1, 1, 1, 1, 1, 1 }, /* <3 */ { 1, 1, 1, 1, 2, 2 }, /* <4 */ { 1, 1, 1, 2, 2, 3 }, /* <5 */ { 1, 1, 2, 2, 3, 3 }, /* <7 */ { 1, 2, 2, 3, 3, 4 }, /* <9 */ { 1, 2, 2, 3, 4, 4 }, /* >9 */ { 2, 2, 3, 3, 4, 4 } };
