CRB Maximized Fireball Trap DC?

[The Roguish Chef]

so the Maximized Fireball Trap on Pg.421 of the CRB has a DC of 14 for it's reflex save, but the magic trap rules state that "If the spell in a magic device trap allows a saving throw, its save DC is (10 + spell level) × 1.5." Now I'm no mathematics wizard but does this equation even make any sense?? Fireball is a lvl 3 spell and maximized metamagic makes it a lvl 6 spell, which would make for a DC of 24 so that's not right but even if I did it 10 + (Spell lvl X 1.5) it would be a DC of 19 not 14, and if the +3 from metal magic is removed (10+3)x1.5 is a DC of 19. something is clearly not right here, even something as simple as the Burning hands trap on Pg.420 would have a DC of 16.5 with this equation, the equation must be 10 +(Spell level x1.5) which would make sense as 10+(3x1.5) rounded down is DC 14. is there an errata on this or am I on my own here to figure out the DCs of these traps?

Based off the other examples of spell traps, looks like it's supposed to be 10 + Floor(Spell Level * 1.5) for the DC.

In regards to maximized fireball, I'll point you to this FAQ.

Essentially

Quote:

In general, use the (normal, lower) spell level or the (higher) spell slot level, whichever is more of a disadvantage for the caster.

So the trap uses the DC of a regular fireball trap instead of a metamagic fireball trap.

Metamagic like Maximize doesn't increase the DC of a fireball so one cast from an item is treated as a 3rd level spell cast with a 13 stat (10 + 3 + 1 = 14) or per the trap rules 10 + (3 * 1.5) = 14.5 which rounds down to 14.
