Your ability with a spell is represented textually by Crawl,
but the relative rankings at the bottom end are not very
intuitive. Here are the rankings in order:
Ranking | Spell failure |
Useless | >100 |
Terrible | 91-100 |
Cruddy | 81-90 |
Bad | 71-80 |
Very Poor | 61-70 |
Poor | 51-60 |
Fair | 41-50 |
Good | 31-40 |
Very Good | 21-30 |
Great | 11-20 |
Excellent | 1-10 |
Perfect | <0 |
The 'spell failure' number is compared to 3d100/3 in order
to determine whether the spell attempt fails or not. Thus a
'Poor/Fair' spell will succeed roughly 50% of the time, an
'Excellent' spell will succeed 99.9% of the time and a
'Terrible' spell will almost always fail.
