Whenever an attack would deal damage to the wielder, there is a 30% chance of that attack being disabled. If the wielder is dealt zero damage from an attack that would have damaged it (such as using False Swipe when the target has 1 HP), except for the effect of a final modifier or the attack itself, Cursed Body will still activate normally. Cursed Body has a separate chance of activation on each hit of a contact multi-hit move, but will not stop any multi-hit move before it has been completed. Does not work if the attack hits a Substitute, but does work if the attacker is behind a Substitute, or if the Pokemon with Cursed Body is knocked out by the attack.
Froslass is extremely frail so is unlikely to make use of the ability, and Jellicent has Water Absorb which is usually considered to be more effective. As well as this, the fact that Disable is a poor strategy which requires a move to be damaging, coupled with the low effect chance, makes it unreliable.
