I've been running a heavily custom game of Starfinder set on Earth in 2045, so their knowledge of magic was very limited.
In the last session they had their first real encounter with magic, and of course their first Mysticism rolls to identify said spells. Now, the DC to identify a spell being cast is "10 + 5 x spell level". In lower levels it's pretty low, 15 or 20 for 1st and 2nd level spells.
But to identify a 6th level spell (the highest on the game) it's a DC of 40. So, at 16th level (when they would probably encounter a 6th level spell for the first time) IF you had a starting INT of 16, AND put all your bonus ability scores on INT until now, AND all the ranks, AND it's a class skill, AND you got a +6 personal upgrade to INT you get a total of +28 and you still need a 12 to identify it... So, less than 50%, even in ideal circumstances.
I was thinking to house rule it back to the Pathfinder style, "15+ 2 x spell level".
Anyone else had the same issue, any other ideas?
