Spells are cast as a skill, with the base difficulty for partial success given by
DC = 15 + Spell level + Effect Modifications
Usually these effect modifications represent a decision to increase the number of targets beyond the basic amount allowed by the spell level; or an attempt to increase duration.
Partial failure occurs if the character rolls below [DC-lvl].
Whether or not a spell is successful on partial failure, partial success or complete success depends on the basic type of spell effect.
Spell Level is unlimited from 0 up and increases or decreases according to the basic type of spell effect, the duration, the range and the area. There are three main types of effects:
• Fixed wondrous effects, such as light, confusion, etc. which are either automatic, or affect enemy creatures in an opposed skill check (Spellcraft vs. Will/Presence etc). Duration of these spells is usually determined by the amount by which the target fails the opposed skill check.
• Variable benefit/damage effects, which manifest as bonuses to a skill or stat, or as damage done/healing. These are characterized by a maximum amount they can attain, and are variable up to the maximum amount. Duration is usually fixed at 1 round per level of the caster.
• Fixed benefit/damage effects, which manifest in the same way as variable effects, but always to a fixed amount. This means that they can work on partial failure, but their difficulty is usually higher. Also, the duration of these spells depends on the degree of success.
Essentially, a spell can have a variable effect for a fixed duration, or a fixed effect for a variable duration.
Table 1 characterises the way in which the three basic types of effects determine success.
Unit of duration: Every spell has a unit of duration determined as part of its creation. This is usually 1 round, but can be in minutes, hours, days, or simply be permanent. For all units of duration except permanent, the spell lasts a period of time equal to some multiplier of the units of duration.

Spell effect only takes hold if
the caster can beat the target on an opposed skill check |
Spell works; fatigue; opposed
skill check DC=die roll. Duration 1 unit of duration per point of failure, +1 |
Spell works; no fatigue;
opposed skill check DC=die roll. Duration 1 unit of duration per point of
failure, +1 |
|
Variable benefit effects
|
Spell only works on partial or
complete success; benefit varies up to some maximum |
Spell does not work; fatigue
|
Spell works; no fatigue;
benefit is given by [spell roll-DC] up to the maximum |
|
Variable damage effects
|
Spell works on partial failure;
damage determined by opposed skill check |
Spell works; fatigue; opposed
skill check DC = die roll. Effect = 1+1/point of failure up to the maximum |
Spell works; no fatigue;
opposed skill check DC = die roll. Effect = 1+1/point of failure up to the maximum |
|
Fixed benefit effects
|
Spell works on partial failure;
benefit is always fixed, but the duration depends on the spell roll |
Spell works; fatigue; full
effect; spell lasts 1 unit of duration |
Spell works; no fatigue; spell
lasts a number of duration units equal to [skill roll-DC]+1 |
|
Fixed damage effects (curses,
etc.) |
Spell works on partial failure;
benefit is always fixed, but the duration depends on the spell roll |
Spell works; fatigue; full
damage; spell lasts 1 unit of duration |
Spell works; no fatigue; spell
lasts a number of duration units equal to [skill roll-DC]+1 |
For the purposes of simple gameplay, we note that spell effects which do stat or skill damage are treated in the same way under these rules as spells that do physical damage. However, this implies that spells which do physical damage will not be permanent. For the purposes of this one type of spell, we assume that the damage effect is permanent. Usually this would require that the spell be considerably higher level than is strictly reasonable, so we waive this consideration for healing and damage spells (see table 3 regarding duration).
Spell Difficulty
Spell difficulty depends on which of the three basic effect types the spell employs.
Variable benefit/damage: Level = [Max effect]/2
Fixed effect/damage: Level = effect

Note that conjuration can be estimated as a DC given by the level of the creature, with a small addition for the conjuration itself (perhaps 1). These levels have been designed to roughly match twice the levels of spells in D&D 3rd edition, with some modifications made possible by doubling the level range. There is no particular reason why the level range should be fixed at 16.
Combining spell effects should use their sum, minus an amount which increases with the levels and numbers of combinations. So for example, daze and knockdown should be level 2; while daze and pain and blindness should be level 6.
Duration
The base unit of duration for all spells is rounds. Spells which do physical damage or which heal people are considered to have permanent base unit of duration, as are spells of abjuration. This is subject to DM discretion. Spells with base duration permanent cannot have their duration reduced.
The base unit of duration can be extended by increasing the level of the spell, as shown in table 3.

Area of effect
Area of effect depends on the domain of the spell. The effects by domain are shown in table 4.

effect

|

|
1 creature
|
|
Abjuration
|
1 creature
|
|
Alteration
|
1 creature
|
|
Evocation
|
3m area
|
The area of effect can be increased by 1 of these base units by increasing the spell DC by 1 freely at time of casting. Evocation can be reduced in size to “beam” (essentially 1 creature) at a DC improvement of 1.
Range
The range also depends on domain, as shown in table 5.
Longer ranges can be obtained by increasing DC by +1 through the categories:
Self / Touch / 10m / 30m / sight.
Evokers and abjurers can step down the range categories to make the DC easier.

Examples
Scorching Ray
Range: 10m, Ranged touch
Max. Damage: variable, max. chosen by caster
Attack: Spellcraft vs. Reflex
DC: 14+ max damage
Area effect: beam (1 target)
This spell has the base range of the evoker type, and variable damage up to the maximum chosen by the caster.
Base range: 0
Reduced area effect: -1 for beam
So in order to do maximum damage of 5 (enough to penetrate most armour) is DC 19.
Magic Missile
Range: sight
Attack: Guaranteed damage
Damage: fixed, 2 wounds
Area effect: single target
DC: 20
For guaranteed damage: +2=+2
Range extension: +2
Area effect reduction: -1
Note that this can be extended to multiple targets (+1 DC per additional target) and increasing the maximum damage by 2 only increases DC by 2.
Sleep
Range: 30m
Area effect: 1 person
Attack: spellcraft vs. will
DC: 20
Sleep is a level 3 effect, +2 for the range extension. This gives a total DC of 20. DC can be increased by 1 per additional target.
————- Footnotes to table 2————–
[1] Assumes that the effect is somehow different to a variable benefit/damage, perhaps because it has penalties which partially offset the benefits
[2] Note Sleep differs from Paralysis: after 1 round, sleepers can be woken non-magically
[3] A minor spell effect is a spell which affects magic – draining charges, protecting against spells, etc. Other spell effects represent progressions from this.
Host armours are designed from a semi-living infernal construct as a heavy-duty harsh-environment armour shell, within which a human soldier can safely nestle. Like all Host Armours, the Cancer Labora enhances the physical and sensory capabilities of its occupant, as well as providing some environmental control and heavy armour. It is intended primarily as a heavy attack unit for dealing with infantry, with its armour thick enough to provide protection against all but the heaviest of infernal weaponry or cannons. The Cancer Labora is made of a type of thick hide modelled on the crab shell, with the plates connected to one another by a special fireproof Infernal material. The human occupant climbs in through the back and operates the various arms using his own hands, and fingers for the smaller arms. The largest arms are weapons in their own right, but can extend small gripping devices to hold additional weapons. The armour shell can also have Infernal weapons embedded, though they must have no recoil. The Cancer Labora is the only Host Armour with an environmental seal suitable for operation underwater, though even then the seal is not perfect and the Labora must return to land within a few hours. In addition to enhanced strength, armour and weapons powers, the Cancer Labora offers nightsight and enhanced hearing magic.
