HW conversions, especially spells

[Herzog]

second list. Note that, as with the OD&D druid summoning spells, summoning spells for druids remain working, reasoning that they worked to begin with because the animals in question are more 'called' by the druid and responding in recognition of the Druid being in tune with nature.
Edit: did the same with ranger summoning spell.
Edit2: Did some reading on the summon animal spells, and I have to come back on my earlier saying on druid summoning spells. They also 'summon' creatures, just not from another plane, but since this is the equivalent of teleportation, they have to go. I also think that this is fair, balance wise.

[Herzog]

Doh!

I just realized I missed a very important keyword in your post, BOZ:
Descriptor

I'll be going over my lists again using your pointers, so expect updates of the old lists.

Also, once I have finished with the working/not working, I will start to split the working list in a known in HW/unknown list.

And, once again, any comment is welcome.

Herzog

 

[BOZ]

yes, the word descriptor was very important. note that "Mind-Affecting spells" covers a very long list!

 

[the Jester]

Read the (OD&D) Hollow World Source books.
I didn't think them up, I just like to convert it to 3.5

I don't have them, unfortunately.

I skimmed the earlier part of the thread again, and I didn't see anything that would bar these... unless they're Mind-Affecting? (I don't think they are, but idhmbifom...)

Oh, or is it just that they're on the list in the sourcebooks..?

 

[BOZ]

Why get rid of things like ventriloquism and ghost sound?

neither are mind-affecting. both are Illusion (Figment) spells, which does not sound like something exluded from the spell lists give what i've seen so far.

 

[Herzog]

Ok, here's the situation:

I tried to check each spell in the 3.5 book against the 'descriptor' rules, while back-referencing the original list in the HW sourcebooks.

I got frustrated pretty fast.

The main problem, I realised after a short while, is that the original list doesn't make much sense. If you look in my posted lists, you see that spells like Floating Disk and Ventriloquism don't work, although I can't think up a single reason why.
Also, a spell like Confusion, Feeblemind and Power Word (although unknown) works normally.

Invisibility-related spells don't work, (both Inv. + detection) but there is no reason why.

And, to top the list, the 'Death Spell' is both listed in the 'Not working' and 'Unknown' spell list.....

So, since the original list doesn't provide much to hold on to, I have to fall back on the general guidelines:

Spells of Holding: Hold Person is Enchantment(Compulsion)[Mind-Affecting].
I thought about making all mind-affecting compulsions not working, but this also would exclude bless and simmilar spells. I checked some of those, and they appear to have the (harmless) description in either saving throw or spell resistance entry.
So, rule 1: All Enchantment(Compulsion)[Mind-Affecting], NOT harmless spells do not function in the Hollow World.

Spells of Charming and Commanding: Charm Person is Enchantment(Charm)[Mind-Affecting].
Although this would disable some spells that used to work (like confusion), in the interest of a 'logical' spell list, I will make rule 2:
Rule 2: All Enchantment(Charm)[Mind-Affecting] spells do not funciton in the Hollow World.
Most of the Commanding spells are Enchantment(Compulsion)[Mind-Affecting], so they fall under rule 1.
However, command undead, plants, etc. have no such descriptor, so, I have to add those somehow to the list.
Rule 3: All spells that somehow take control over a creature (typically having the word 'control' or 'command' in the spell name or description) do not function in the Hollow World.

Spells of Divination and Communication: This spell includes (in OD&D) know alignment, but NOT Detect Evil. A quick reminder: OD&D only recognized Law/Chaos as alignment axis.
It typically includes spells that require mindreading or cross-planar communication (contact with immortals...)
Trying not to exluce all divination spells, the rule becomes:
Rule 4: All Divination spells Requiring communication with a being on another plane do not function in the Hollow World.
This requires a bit of DM's discretion. If the material component require 'an offering apropriate to your religion', assume a diety or immortal is involved. Throwing stones or bones does not require communication. (Compare 'Divination' and 'Augury')
Rule 5: All Divination[Mind-Affecting] spells do not function in the Hollow World. Note: I only found one(Detect Thoughts).

This still does not exclude a spell like 'speak with the dead', but the description of that spell states that you are semi-animating the corpse, not contacting the soul of the corpse, so I'll let that one function.

Spells of Immortality: This should include all spells that bring you back from the dead. I could use the 'Healing' subdomain as an indication, but that would exlude a lot of other spells that I think you want to keep.
I have therefore come to the following rule:
Rule 6: All spells that function by inserting a 'soul' into a body do not function in the Hollow World. Note that this would include 'Magic Jar' in a rather unpleasant way: you can leave your body to posses the 'jar', but cannot return to your body.( A slight alteration from the original rules, but logical nonetheless I think.)

Spells of Instantaneous Transportation: This includes both spells that require planar travel as the instant teleportation of persons and objects.
Most spells are quite clear on the subject, but I haven't checked them all. If you find an inconsistency, please tell me:
Rule 7: All spells that have the (Teleport) descriptor and all spells that function through planar travel (including to the ethereal plane) do not function in the Hollow World.

Spells of Summoning: This includes (in the OD&D system) all spells that summon or create creatures.
As most 'creation' spells would allready fail under rule 6 (requiring a 'soul' to enter the new body) they are already covered. As far as I can tell all summoning spells have the 'Summoning' descriptor, so:
Rule 8: All spells that have the (Summoning) descriptor do not function in the Hollow World.
Note that 'Unseen servant' has replaced 'Invisible stalker', and is now a 'mindless, shapeless form' instead of an actual summoned being. It therefore functions in the 3e HW, where its OD&D counterpart did not.

I will be going over the complete spell list somewhere in the coming week, to see what spells seem to slip through my rules, but if it's just one or two I think I leave it at this. (Note: I'm not sure what to do with Invisibility spells yet.)


<Note: I will edit this post later with additions if I should find some. feel free to comment in the meantime>

[BOZ]

sounds like you're figuring it out pretty well now.
