Destroy Minor Helm

If cast on a minor helm, it utterly destroys the helm seat and the spelljamming magic. The helmsman operating the helm at the time suffers electrical damage equal in effects to a spark burst (1d3 points of damage, plus 1 per caster level; 1d4 points of damage in the phlogiston; each 10 points inflicts 1 point of hull damage). Further, the helmsman must make a saving throw vs. spell or be rendered unconscious for 1d4 turns and unable to cast or regain spells for 1–3 days.

Lifejammers, pool helms, and series helms are utterly destroyed by this spell. Beings in those helms suffer the same damage as those using a minor helm, except that a lifejammer receives a beneficial discharge of energy; typically regaining 2-8 hit points at the same time as the unfortunate being is harmed by the helm's explosion.

The spell renders foundries and furnaces inoperative for 1d4+1 rounds.

The spell disables a major helm for 1-2 rounds (the helmsman must save vs. spell to avoid a 1d4 hit point loss and 1 round of unconsciousness; if successful, no damage is taken). If cast on a major helm or death helm, this spell reduces the target's Ship Rating (a measure of speed) by 1 point for 1d12 turns. Multiple castings cause overlapping and cumulative effects.

The spell's material component is a pinch of dust, which must have once been part of a magical item, or which has received a long-lasting dweomer.

Notes: Common for spellcasters from a spell-jamming culture; otherwise rare.
