The number of chitin scraps you receive from damaged chitin varies with your smithing level, using the following formula:

\text{Scraps} = \lfloor L \times 0.5 \rfloor - 9

Enter your Smithing level name=skillstat_Smithing_level|type=int|value=1|range=60,99|sublist=calcchitin name=scraps|type=output

let( sm, skillstat_Smithing_level ) let( make, floor(21 + ((sm - 60) / 2)) ) let( scraps, "At a Smithing level of " + sm + ", you will make " + make + " scraps per piece of damaged chitin." )
