New Spell: Thunderwave

Thunderwave
Spell Level: Druid 3
Range: Self
Duration: Instant
Similar to the shockwave spell, once the Druid completes the casting he raps his staff or cudgel on the ground. The sound caused from the rap is increased many-fold into a thunderous boom that affects every creature in a 10 ft radius around the Druid. Victims suffer 1d6 points of damage plus an additional 1d6 per 4 caster levels. If the victims fail a Toughness saving throw, they are struck deaf as well. A silence spell or similar effect will negate this spell for anyone within its area of effect.

Nimbus of Saints*

Nimbus of Saints*

Spell Level: Cleric 3

When cast, a halo of light (or darkness) forms over the Cleric’s head. For the spell’s duration, any healing spell cast within 10 ft of the Cleric (including his own) gain an extra die.

New Cleric Spell - Undeath to Death

Undeath to Death

Spell Level: Cleric 3

Range: Self

Duration: Instant

When the Cleric holds his holy symbol aloft and utters the prayers of his Deity, a wave of divine energy issues forth. All undead in a 30 ft radius of the Cleric suffers 1d4 points of damage per caster level (maximum of 10d4), with a Toughness saving throw allowed for half damage. Any undead of HD under half the Cleric’s level that are killed are turned to dust.

Shadow Bolt

Illusionists dabble in more than merely the mind - they depend wholly on as much local conditions as much to produce magical effects that seem believable so their opponents believe they are real. Some of their magic comes from places and planes of eternal twilight and shadow however. Because they access these planes moreso than a Magic-user manipulates the Ether, they can turn seemingly innocent or harmless things into semi-real and highly dangerous things.

Shadow Bolt
Spell Level: Illusionist, 3rd Level
Range: 40 ft
Duration: Immediate

When cast, the Illusionist throws a crackling bolt of charged shadow energy 30 ft in length that follows the same rules as per a lightning bolt with respect to obstructions. Victims in the path of the Shadow Bolt recieve 1d4 points of shadow energy damage per level of the Illusionist and are blinded for 1d4 rounds. Victims succeeding a Toughness saving throw recieve half damage and are blinded for 1 round.

Resist Lightning

I don't know why, but it seems like the early editions of D&D (and their retro-clones) forgot all about lightning and electricity. There are attack spells to inflict it, but the elemental defensive spells only protect against Cold and Fire damage. So, The Druids of Onn have a spell to help survive those dangerous attacks, Resist Lightning:

Resist Lightning
Spell Level: Druid, 3rd Level
Range: Touch
Duration: 12 turns

Resist Lightning halves any lightning-based damage the recipient takes as well as granting a +3 bonus to saving throws to resist lightning-based effects.
