Greetings,
I've looked high and low for an answer. Now I am here.
If you were to take a look in the NPC Codex at the stat blocks of, for example, a couple of Illusionist NPCs, specifically, Prankster Illusionist (p.185) and/or Black Ice (p.238), you would find in one or two of their Spells a single digit instead of the DC, or in addition to the DC. For instance, with Prankster Illusionist, look at color spray:
1st -- color spray (2, DC 17)
While in Black Ice, you'll see:
2nd -- invisibility (2) and
1st -- magic missile (2)
Can someone tell me what those digits signify? Both by themselves, and with the DC?
Thanks!
