Concussion

Concussion is a missile-type Sound- and Air spell that creates a ball of highly pressurized air. When this air strikes a target, it explodes. Anyone within 10 yards of this explosion must roll against HT-3 or be physically stunned -- those stunned this way may roll HT-3 once per second to recover.Magic, p.26
Low-tech hearing protection (such as stuffing one's ears with whatever's available) can give a bonus to resist stunning at +1 per -1 to Hearing rolls, maximum +5.DFRPG: Spells, p.15 Protected Hearing gives a +5 bonus to resist this spell, while Resist Sound provides true immunity temporarily.

== Trivia ==
=== Concussion Discussion ===
Concussion is one of the Missile Spells which doesn't have Magery 1 as a prerequisite, nor do any of its parent prerequisite spells, such as Seek Air and Sound. This notably differs from other missile spells, such as Fireball. Presumably this would allow it to be cast by a character with Magery 0, or even non-mages in high mana.

:basically "from 1 to level" is from 1 to 0 at level 0, 1 to 1 at level 1, or 1 to N at level N = 2 or higher. The first two cases can be summarized as "1." :Concussion is indeed an oversight; call it 2 instead of 1, since explosive Missile spells are really just double-cost Missile spells.
This is a flip-flop from his earlier 2006 ruling at r prerequisites. In a high-mana region, a non-mage could cast these spells. Since missile spells can be powered up at a rate dep
:Twice zero is still zero. If you don't have at least Magery 1, these spells aren't useful to you, even if you can cast them.
