Does anybody know how this is calculated? I’m asking because I’m running into a lot of creatures that I can’t extract from despite having C level knowledge in them.
Generally the lowest it will go is 50% for creatures that need D or C knowledge level to extract, and certain factors/items can improve this chance up to 100%.
If it says “this creature is special” when highlighted, then it can never be extracted from.
EDIT: There is one exception to the Special Creature rule - if it is singular, then any extraction limitations/restrictions are overridden and you can extract it freely.
