What happens when a necklace of fireballs detonates when worn?

[Nail]

In any case, if it's a cursed necklace, you're perfectly allowed to simply disallow the reflex save as part of the effect of the curse.

You're also allowed to make an item that doesn't suck.

Include the Ref save, and slap on a circumstance penalty.

A bit harsh. A Necklace of Fireballs Type 1 is only 8d6 (5d6 + 3d6) total, avg of 24 dmg with no save isn't all that much suck.
