RPG Mechanics VI

Now I’m going to have a look at different weapons and their effects. In basic LL all weapons do D6 but I can pretty confidently say most people will play with the variable damage options. So most one handed swords do D8, maces and axes do D6, daggers and other small or light weapons do D4 and 2 handed swords do D10.

So I calculated some damage ratios and plugged them into the hit ratio matrix thus:

D6 vs D8	B-hit	11	10	9	8	7	6	5	4	3	2
A-hit		0.5	0.55	0.6	0.65	0.7	0.75	0.8	0.85	0.9	0.95
11	0.5	0.78	0.64	0.52	0.42	0.33	0.26	0.20	0.14	0.09	0.04
10	0.55	0.95	0.78	0.64	0.51	0.41	0.32	0.24	0.17	0.11	0.05
9	0.6	1.17	0.96	0.78	0.63	0.50	0.39	0.29	0.21	0.13	0.06
8	0.65	1.45	1.19	0.97	0.78	0.62	0.48	0.36	0.26	0.16	0.08
7	0.7	1.82	1.49	1.21	0.98	0.78	0.61	0.46	0.32	0.20	0.10
6	0.75	2.34	1.91	1.56	1.26	1.00	0.78	0.59	0.41	0.26	0.12
5	0.8	3.12	2.55	2.08	1.68	1.34	1.04	0.78	0.55	0.35	0.16
4	0.85	4.42	3.62	2.95	2.38	1.89	1.47	1.11	0.78	0.49	0.23
3	0.9	7.02	5.74	4.68	3.78	3.01	2.34	1.76	1.24	0.78	0.37
2	0.95	14.82	12.13	9.88	7.98	6.35	4.94	3.71	2.62	1.65	0.78

Which converts to an offset matrix:

D6 vs D8		L 0	L 1,2	L 3	L 4	L 5	L 6	L 7,8	L 9	L 10,11	L12
		11	10	9	8	7	6	5	4	3	2
L 0	11	0	1	1	1	1	1	2	2	2	3
L 1,2	10	0	0	1	1	1	1	2	2	2	3
L 3	9	0	0	0	1	1	1	1	2	2	3
L 4	8	0	0	0	0	1	1	1	1	2	3
L 5	7	-1	0	0	0	0	1	1	1	2	2
L 6	6	-1	-1	0	0	0	0	1	1	1	2
L 7,8	5	-1	-1	-1	-1	0	0	0	1	1	2
L 9	4	-2	-1	-1	-1	-1	0	0	0	1	2
L 10,11	3	-2	-2	-2	-1	-1	-1	-1	0	0	1
L 12	2	-3	-3	-2	-2	-2	-2	-1	-1	-1	0

Which can be compared to the original d8 vs d8 matrix:

D6 vs D8		L 0	L 1,2	L 3	L 4	L 5	L 6	L 7,8	L 9	L 10,11	L12
		11	10	9	8	7	6	5	4	3	2
L 0	11	0	-1	-1	0	0	0	-1	0	0	0
L 1,2	10	0	0	-1	-1	0	0	-1	0	0	0
L 3	9	0	0	0	-1	-1	0	0	-1	0	0
L 4	8	-1	0	0	0	-1	0	0	0	0	-1
L 5	7	0	-1	0	0	0	-1	0	0	-1	0
L 6	6	0	0	-1	-1	0	0	-1	0	0	0
L 7,8	5	-1	0	0	0	-1	0	0	-1	0	0
L 9	4	0	-1	0	0	0	-1	0	0	0	-1
L 10,11	3	0	0	0	-1	0	0	0	-1	0	0
L 12	2	0	0	-1	0	0	0	-1	0	0	0

That looks like a D6 weapon has a -1 level disadvantage against a D8 weapon.

Similarly we can compare D10 and D4 weapons:

D10 vs D8		L 0	L 1,2	L 3	L 4	L 5	L 6	L 7,8	L 9	L 10,11	L12
		11	10	9	8	7	6	5	4	3	2
L 0	11	0	0	0	1	1	0	0	1	0	0
L 1,2	10	1	0	0	0	1	0	0	1	0	1
L 3	9	1	1	0	0	0	1	0	0	1	1
L 4	8	0	1	1	0	0	1	1	0	1	0
L 5	7	0	0	1	1	0	0	1	0	0	0
L 6	6	1	0	0	0	1	0	0	1	0	0
L 7,8	5	0	1	1	0	0	1	0	0	1	1
L 9	4	0	0	1	1	0	0	1	0	1	0
L 10,11	3	1	0	0	0	1	1	0	0	0	1
L 12	2	0	0	0	1	1	0	0	1	0	0

D4 vs D8		L 0	L 1,2	L 3	L 4	L 5	L 6	L 7,8	L 9	L 10,11	L12
		11	10	9	8	7	6	5	4	3	2
L 0	11	-1	-1	-1	0	-1	-1	-1	0	-1	0
L 1,2	10	0	-1	-1	-1	0	-1	-1	0	-1	0
L 3	9	0	0	-1	-1	-1	0	-1	-1	0	0
L 4	8	-1	0	0	-1	-1	0	0	-1	0	-1
L 5	7	-1	-1	0	0	-1	-1	0	-1	-1	-1
L 6	6	0	-1	-1	-1	0	-1	-1	0	-1	0
L 7,8	5	-1	0	-1	-1	-1	0	-1	-1	-1	0
L 9	4	-1	-1	0	0	-1	-1	0	-1	0	-1
L 10,11	3	0	0	-1	-1	0	0	-1	-1	-1	0
L 12	2	-1	-1	-1	0	0	-1	-1	0	-1	-1

So …

Calculate your Fighter equivalent level ( Cleric or Thief = x 0.67, Magic User = x 0.5 ),

Add 9 – your armour class,

Subtract 2 if using a D4 weapon, 1 if using a D6 weapon or add 1 if using a D10 weapon,

Divide total by 4 truncating to an integer ( I’m going to count the possible -1 as 0 ).

At this point I’m still just converting Labyrinth Lord as a sanity check. At some point soon I’m going to move in my own direction.

Shock

We just heard this morning that an old friend Judith Hanna, who Maureen has known for decades, has had her cancer reassessed as incurable and been offered palliative care. Judith had recently had breast cancer and initial treatment results were positive but you never know for sure with cancer.
