Several combat stats in ToME are rescaled to produce dimishing returns. The rescaling system uses 5 tiers, with increasing costs. A raw input value is converted to a final (effective) value according to the following system:
| Tier | Final Values | Cost per point |
|---|---|---|
| Tier 1 | 0 to 20 | 1 |
| Tier 2 | 21 to 40 | 2 |
| Tier 3 | 41 to 60 | 3 |
| Tier 4 | 61 to 80 | 4 |
| Tier 5 | 81+ | 5 |
Examples:
| Raw Input | Final Value | Tier |
|---|---|---|
| 17 | 17 | 1 |
| 50 | 35 | 2 |
| 71 | 43.66 | 3 |
Accuracy, Defense, Physical Power, Spellpower, Mindpower, Physical Save, Spell Save and Mental Save are all rescaled this way.
