Detect magic, greater says:
You can recognize this signature if you succeed at a Spellcraft check when later identifying a spell to determine whether or not that spell was cast by the same individual.
I am confused what is the mechanic for the DC and other functions for identifying spells signature features:
- isn't it supposed to be a knowledge (arcana) to recognize spells currently in effect?
- is the DC calculated using spellcraft skill's "identify spell as it being cast" math or the one presented previously on the spell regarding "identify last spell cast by creature" effect of the spell?
