For a 'realistic' game, weapons which do 6dx100 are fine. For a more cinematic game, you may want things to work differently. LGDS treats all damage as being logarithmic. When converting gadgets, vehicles, animals, and the like, use the conversion below (characters are converted differently). DR/T is DR + sqrt(hit points), and is 3 for a typical human (use 3 for ultra-tech equipment).
| Old Damage | 1d | 1d+1 | 1d+2 | 2d | 2d+2 | 3d+1 | 4d | 5d | 6d | 8d | 10d |
| New Damage | 1d | 1d+1 | 1d+2 | 2d-1 | 2d | 2d+1 | 2d+2 | 3d-1 | 3d | 3d+1 | 3d+2 |
| Old Damage | 13d | 16d | 20d | 25d | 32d | 40d | 50d | 63d | 80d | 100d | x100 |
| New Damage | 4d-1 | 4d | 4d+1 | 4d+2 | 5d-1 | 5d | 5d+1 | 5d+2 | 6d-1 | 6d | +5d |
| Old ST | 10 | 13 | 16 | 20 | 25 | 32 | 40 | 50 | 63 | 80 | x10 |
| New ST | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | +10 |
| Old DR/T | 3 | 4 | 5 | 6 | 8 | 10 | 13 | 16 | 20 | 25 | x10 |
| New DR | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | +10 |
When converting characters, do not use this system. Character conversion is instead done as follows:
| Magic | Do not convert. Listed effects are fine. |
| Fantasy/Medieval Equipment | Do not convert. |
| Super-ST | For ST up to 30, do not convert. For ST greater than 30, change to 27 + ST/10 (i.e. cost of +1 ST is a flat 5/level) |
| Super-DR | Divide by 4 |
| Super-Atk | Divide dice by 4. 1/4d = +1, 1/2d = +2, 3/4d = +1d-1 |
Some more convenient rules of thumb:
For objects, figure out the stats of a size-0 object (using the DR/T formula above), and add +2 DR per +1 size modifier. A typical size-0 boulder has DR 8 and HT 10, a size-0 statue has DR 4 and HT 10.
For lifting objects, figure out the ST required to lift a size-0 object, and add +5 ST per +1 size. A typical size-0 boulder requires ST 18. With +1 ST, you can carry it as extra-heavy load, with +3 ST as heavy load, with +6 ST as medium load (or lift one-handed), with +8 ST as light load, with +11 ST as no encumbrance.
