Just some spells created by me for kilgs's RPOL Tal game using 5th Edition rules. I had a lot of fun coming up with them, please feel free to use them yourselves if you like and drop me a line with your opinions if you like as well...

Malifex's Grimoire:

Attack Spells:
Blood Call
Duration: Instant
Range: 50 feet
Base Difficulty: -1 (level 1 base)
When the necromancer finishes casting this spell he pricks his finger, lets a drop of blood fall to the ground, then stretches out his hands; beckoning to the target. At this time the target feels a surge within his body as blood comes out from the eyes, nose, mouth, ears, and any open wounds. The blood runs down the body almost as if alive and moves towards the drop of blood the necromancer let fall, reaching it by the end of the round unless absorbed by the terrain. This blood loss causes 1 hp of damage per spell level and makes the target weak and unsteady for a moment. This spell is ineffective against anything that doesn't bleed.

Bone Spike (unique spell)
Duration: Instant
Range: 200 feet
Base Difficulty: -5 (level 1 base -3 Tractus <1 step> -1 range)
Upon completing this spell the necromancer points at the target while brandishing a shard of bone. A spike of bone shoots from the necromancer's outstretched finger and impacts the target dealing  1 hp of damage per spell level. After impacting the target the spike splinters into hundreds of tiny bone shards.

Breath of Pestilence
Duration: Instant
Range: 30 feet
Area of Effect: 4 foot radius cone 30 feet long
Base Difficulty: -6 (level 1 base -5 area)
After completing the incantation the necromancer breathes out a ghastly greenish-brown cloud of vapors that fills a cone 30 feet long and 8 feet across. These vapors are composed of virulent pestilence that ravages those within it for 1 hp of damage per spell level. The cloud smells vaguely of rot and corruption and hangs in the air for 1 round before dissipating although it does no further damage than the initial exposure. Due to the nature of the spell it ignores armor protection but does not harm anything that doesn't breathe.

Malifex's Storm of Maggots
Duration: Instant (1 round effect)
Range: 50 feet
Area of Effect: 1 foot radius
Base Difficulty: -5 (level 1 base -1 area -3 difficulty)
Upon finishing the incantation, the necromancer throws the corpse of a small animal/bird/reptile at the enemy. As the corpse reaches the target it explodes into a shower of reeking, writhing maggots. These maggots voraciously burrow into the victim for 1 round, dealing 1 hp of damage per spell level. The victim must make a CON check at -1 per 5 spell levels or be unable to act for 1 round due to retching uncontrollably at the stench and sensation of the maggots. Note that this spell has no effect on constructs, spiritforms, and the undead.

Malifex's Soulwrench
Duration: Instant
Range: 50 feet
Base Difficulty: -1 (level 1 base)
Upon casting this spell a black blot of necromantic energy leaps from the caster's palm. Upon striking the target this spell inflicts 1 hp of damage per spell level, crushing the very life force of the victim. This wrenching staggers the victim who takes a -1 penalty per 3 spell levels to all actions for 1 round. Note that this spell has no effect on constructs.

Conjuration Spells:
Malifex's Bone Armor
Duration: 5 minutes
Range: 50 feet
Base Difficulty: -1 (-4 duration +3 Order bonus -weight & PR of armor)
When this spell is cast a suit of bone armor forms around the body of the caster or any recipient within range. The bone armor functions exactly the same as the type of armor it is based upon, giving the same PR but also having the same weight and STR requirement. The wearer also takes any DEX related penalties from the armor. As an example bone scale (scale armor) would have a PR of 5, a weight of 35lbs, and a STR requirement of +1. The armor would add -9 to the base difficulty (-5 for PR and -4 for weight).

Malifex's Cloud of Rot
Duration: 2 minutes
Range: 50 feet
Base Difficulty: -1 (level 3 base -1 duration +3 Order bonus)
This spell conjures a cloud of rotting corpse stench 3 cubic feet (+1 cubic foot per additional spell level) in size that emanates from the casters fingertips and coalesces at the desired range. The cloud is not deadly, but it will incapacitate targets within the area of effect, making them unable to act due to wretching and vomiting. Victims may resist by making a CON check at –1/3 the spell's level. Note that this spell has no effect on constructs, spiritforms, and the undead.

Enchantment Spells:
Fleshgird
Duration: 2 minutes
Range: Touch
Base Difficulty : -4 (level 3 base -1 duration)
With this enchantment the necromancer reaches out to the shadow to bolster the life force of himself or the recipient. The necromancer or recipient gains 1 hit point per 3 spell levels as the flesh is infused with shadowstuff. Damage done to the recipient comes off of these hit points first. The recipient of this spell is shrouded by faint whisps of shadow that swirl around until the spell ends or is dispelled by damage.

Malifex's Otherwordly Grace
Duration: 2 minutes
Range: Touch
Base Difficulty: -6 (level 5 base -1 duration)
Upon completing the spell the necromancer or recipient's body is infused with the uncanny grace of a shadowcat, enhancing the necromancer's DEX by +1 per 5 spell levels. The side effect of this spell is that the caster or recipient's face takes on dark, shadowy, cat-like features for the duration of the spell.

Malifex's Spectral Girding
Duration: 2 minutes
Range: Touch
Base Difficulty: -3 (level 3 base -1 duration)
This incantation allows the necromancer to bolster the strength of his or a recipient's flesh with necromantic energy, granting a PR of +1 per 3 spell levels. The side effect of this spell is that the recipient's flesh becomes grey and wizened, not unlike that of a mummified corpse.

Undeath's Blessing
Duration: 3 minutes
Range: Touch
Base Difficulty: -5 (level 3 base -2 duration)
Invoking this spell infuses the necromancer or recipient with the durability of the undead, granting a bonus to CON of +1 per 3 spell levels but only in regards to wounds and death saves. The recipient's SPD is reduced by -1 due to the numbing effects of the spell.

Undeath's Vitality
Duration: 2 minutes
Range: Touch
Base Difficulty: -6 (level 5 base -1 duration)
Upon completion of this spell the necromancer or recipient's muscles are girded with necromantic power, increasing the necromancer's STR by +1 per 5 spell levels. The side effect of this spell is brief intense pain as grey, withered muscles and sinews attach themselves all over the recipient's body, melding into the flesh.

Unearthly Spiritual Hunger
Duration: 2 minutes
Range: Touch
Base Difficulty: -6 (level 5 base -1 duration)
This spell infuses the necromancer or recipient with the sensory abilities of a ghast. The necromancer or recipient's eyes and face take on a maniacal and wild appearance and allows the recipient to notice living and spiritual energies and movement in the area by heightening the sight, smell, and hearing abilities of the recipient. This spell grants a bonus of +1 per 3 spell levels to PER specifically in regards to detecting hidden or invisible beings (including ambushes). It can also help penetrate illusions of creatures that do not have all the senses listed.

Transmutation Spells:
Fleshmold
Duration: 3 minutes
Range: Touch
Base Difficulty: -3 (level 3 base -2 duration +2 Order bonus)
This spell allows the necromancer to mold the shape of himself or another recipient into a different form; ranging from minor alterations in appearance to the complete alteration of form and being. This spell is incredibly disturbing for others to watch due to the sights and sounds of flesh stretching and bones cracking and popping under the strain of the transformation. Alteration of form takes 1 minute which does not include the duration of the spell itself. Unwilling recipients of this spell may make a CON roll at -1 per 3 spell levels to resist the transformation.

Malifex's Rotting Touch
Duration: Instant
Range: Touch
Base Difficulty: -2 (level 1 base +2 Order bonus -3 difficulty)
Upon completing this enchantment and touching the victim, necrotic energy will flow out into the victim's flesh. This causes 1 hp of damage per spell level as the victim's flesh dies, putrefies, then falls away. This causes great pain to the victim who must make a CON check at -1 per 3 spell levels or be unable to act for 1 round due to the intense pain. Note that this spell has no effect on constructs, spiritforms, and undead who have no living flesh to rot away.

Staring Through the Eyes of the Dead
Duration: 3 minutes
Range: Touch
Base Difficulty: -10 (level 10 base -2 duration +2 Order bonus)
Upon casting this spell the necromancer causes his or another target's eyes to take on a cold, vacant gaze. This enables the necromancer or target to see in the dark as a necrophage would. Living creatures seen in the dark appear to glow faintly as if the eyes are seeing the very life energy of the creature. The black empty stare of the recipient's eyes is unnerving to those who view it, giving a -2 to reaction rolls and a +2 to intimidate.

Ward Spells:
Malifex's Corporo-Spiritual Bulwark
Duration: 2 minutes
Range: Touch
Base Difficulty: -2 (level 1 base -1 duration)
Upon casting this spell the necromancer is shrouded in shadows from the nether realms. These shadows block the magical assaults of other casters, creating a ward vs. Attack spells having 2 PR and 2 hp rating per spell level.

Undeadbane
Duration: 2 minutes

Base Difficulty: -2 (level 1 base -1 duration)
When casting this spell the necromancer calls upon the strength of his own lifeforce to protect him from the cold touch of the undead.

Weaken the Spirit
Duration: 2 minutes
