Previously, I calculated the point costs of the abilities in Psionic Powers. Today’s post does the same for Thaumatology: Sorcery. As with the Psionic Powers version, I only recalculated the costs and made no other changes, and I left certain leveled abilities unrounded. I also used the Psionic Powers version of calculating the cost of Innate Attacks with partial dice because it is easier. That may also introduce a slight difference in cost if Sorcery doesn’t do it too.

Air Spells

Air Jet

Additive: 6/level

Multiplicative: 3.2375/level

No-Smell

Additive: 63

Multiplicative: 52

Animal Spells

Animal Control

Additive: 10

Multiplicative: same

Repel Animals

Additive: 47 + 5/additional level

Multiplicative: 43.35 + 4.25/additional level

Body Control

Haircut

Additive: 11

Multiplicative: 3

Note: Under Additive Modifiers, Haircut would be a candidate for hardcore improvisation. With Multiplicative Modifiers, it is a good cost for normal improvisation. In neither case would a PC normally take it as a known spell.

Tanglefoot

Additive: 30

Multiplicative: 8

Communication and Empathy

Gift of Tongues

Additive: 28

Multiplicative: 26

Sense Life

Additive: 26 or 56

Multiplicative: 26 or 51

Earth

Flesh to Stone

Additive: 61

Multiplicative: 40

Walk Through Earth

Additive: 56 or 72

Multiplicative: 49 or 61

Note: This conversion was tedious since it required calculating Affliction, Walk Through Earth and Improved Walk Through Earth.

Enchantment

Enchant

Additive: 37

Multiplicative: 8

Note: You can take off the 1/day for the same cost. You can even remove the character point cost for 38 points! GMs should think twice before changing this too much.

Penetrating Weapon

Additive: 44 + 16/additional level

Multiplicative: 28.223 + 7.04/additional level

Notes: Imbuement based Weapon Buff advantages cost 19.36, 22.8 or 29.92 + 7.04/level using Multiplicative Modifiers. The cost listed above is entirely unrounded, so actual cost would be a bit higher. Technically, the buff advantage should be calculated, rounded then applied as an enhancement to the Affliction, but that is too much effort. 29 + 8/additional level is easier.

Fire

Ignite Fire

Additive: 1 or 4

Multiplicative: 1 or 2

Shape Fire

Additive: 19/level

Multiplicative: 15.4/level

Gate

Planar Visit

Additive: 30 or 50

Multiplicative: 22 or 44

The basic version hits the -80% limitation limit exactly while the improved version drops the limitation to -60%.

Suspend Time

Additive: 141 + 5/additional level

Multiplicative: 107.625 + 3.75/level

Note: Suspend Time is a great candidate for additional limitations.

Healing

Minor Healing

Additive: 32

Multiplicative: 18

Relieve Madness

Additive: 10

Multiplicative: no change

Illusion and Creation

Complex Illusion

Additive: 42 + 12.5/additional level

Multiplicative: 38.25 + 10.625/additional level

Create object

Additive: 56 + 4/additional level

Multiplicative: 41.6 + 1.6/additional level

Knowledge

Detect Magic

Additive: 7

Multiplicative: no change

Divination

Additive: 48 or 98

Multiplicative: 20 or 35

Note: The -70% limitations combined with the improved version having an enhancement explains the cost difference.

Light and Darkness

Light

Additive: 11 + 4/additional level

Multiplicative: 8 + 2/additional level

Sunbolt

Additive: 4/level

Multiplicative: no change

Making and Breaking

Disintegrate

Additive: 47

Multiplicative: 38

Inspired Creation

Additive: 30

Multiplicative: 27

Note: Inspired Creation’s buff advantage has no enhancements, so this calculation was relatively simple.

Meta

Dispel Magic

Additive: 60 + 25/additional level

Multiplicative: 24.375 + 6.25/additional level

Remove Curse

Additive: 65

Multiplicative: 21

Scryguard

Additive: 68

Multiplicative: 57

Mind Control

Lesser Geas

Additive: 54

Multiplicative: 48

Note: This one has a built in Limited Enhancement! These would be more common for abilities designed for use with Multiplicative Modifiers to limit abilities while avoiding the -80% limitation cap.

Terror

Additive: 45 + 15/additional level

Multiplicative: 42.075 + 14.025/additional level

Movement

Grease

Additive: 45 + 15/additional level

Multiplicative: 30 + 6/additional level

Note: This is quite a bit less costly. The extra levels do exceed the -80% cap slightly.

Locksmith

Additive: 10

Multiplicative: no change

Necromantic

Steal Vitality

Additive: 19 + 3/additional level

Multiplicative: no change

Turn Zombie

Additive: 47 + 7.5/additional level

Multiplicative: 7.875 + 10 + 1.25/additional level + 1/additional level

Plant

Blight

Additive: 44 + 5/additional level

Multiplicative: 22.275 + 2.25/additional level

Body of Wood

Additive: 98

Multiplicative: 85

Note: The Body of Wood meta-trait doesn’t change with Multiplicative Modifiers.

Protection and Warning

Magelock

Additive: 25 + 15/additional level

Multiplicative: 7 + 3/additional level

Notes: This one exceeds the -80% limitation limit. The added DR has a limitation but no enhancement, so its cost doesn’t change.

Reverse Missiles

Additive: 75 + 63/additional level

Multiplicative: 51.425 + 39.95/additional level

Note: This cost is decreased significantly. The -40% on the Reverse Missiles advantage is significant.

Sound

Delayed Message

Additive: 38

Multiplicative: 34

Thunderclap

Additive: 36 + 5/additional level

Multiplicative: 25 + 3/additional level

Technology

Awaken Computer

Additive: 45/level

Multiplicative: 40.5/level

Preserve Fuel

Additive: 45 + 5/additional level

Multiplicative: 22.725 + 2.25/additional level

Water

Icy Weapon

Additive: 14

Multiplicative: 12

Note: Unlike the Imbuement based Weapon Buffs, this one has no enhancements in the buff advantage (besides the +0% one that doesn’t change cost).

Whirlpool

Additive: 6/level

Multiplicative: 2.8/level

Weather

Cool

Additive: 7 + 5/additional level, 14 + 10/additional level, 21 + 15/additional level, 28 + 20/additional level or 35 + 25/additional level

Multiplicative: 4.725 + 1.75/additional level, 9.45 + 3.5/additional level, 14.175 + 5.25/additional level, 18.9 + 7/additional level or 23.625 + 8.75/additional level

Notes: This one was obviously one of the more tedious conversions. It is significantly less costly and does exceed the -80% limitation cap.

Predict Weather

Additive: 13 or 25

Multiplicative: 8 or 11

Multiplicative Sorcerous Empowerment

Sorcerous Empowerment is its own advantage, but what would its cost be if designed using Multiplicative Modifiers? This is more for fun than a recommendation. See the Under the Hood box on Thaumatology: Sorcery p. 5 to see how this is done.

Multiplicative Sorcerous Empowerment: 17.6 + 8.8/additional level

This isn’t much of a difference. I suggest sticking to the pentaphilic version. It would make regular Improvisation less costly, but Known Spells and Hardcore Improvisation both rely on total cost.

Final Thoughts

These calculations were much simpler than the Psionic Powers ones although there may be a few errors. The most complicated part was remembering to use the Multiplicative Modifiers for the advantage bestowed by the buffs before calculating Affliction’s cost.

Multiplicative Modifiers has the potential to incentivize designing spells with more restrictive rituals such as Requires Gestures, Requires Magic Words, Requires Material Component, etc. or limitations meant to make Sorcery act more like Magic as Skills magic such as Requires (Attribute) Roll, Short-Range, etc. Some existing spells could benefit from those limitations, but many already hit the -80% limitation cap.

Multiplicative Modifier Sorcery would benefit from spells designed with said modifiers in mind.

Some abilities may be designed differently if intended for use with Multiplicative Modifiers, but these worked fairly well. I will leave converting Enraged Eggplant’s collection to someone else.
