House Rules

( ⇪ Game Feel )

In-general, Hyperion Voyages uses all of the house-rules written in the “Maginomicon’s D&D 3.5 House Rules” document. Please look through that first regarding overall house rules that aren’t necessarily specific to this setting.

House Rules Document Excerpts

Unreasonable Consequences
Learning Opportunities for Spells and Powers (all spellcasters/manifesters should read this)
Banned Stuff (all PCs must read this in addition to the Recommended Bans below)
Real Alignments (all PCs must read this)
Clarifications on Consumables and Containers
Clarifications on Light and Darkness
Clarifications on Passive Senses
Item Clarifications
Action Economy (all PCs would be well-advised to read this)
Critical Hits and Fumbles (all PCs should read this section, but you can skip the tables)
Line of Effect vs Line of Sight (mostly only relevant if you’re a spellcaster or psionicist)
Class Fixes (all PCs should check this for any fixes for their class)
Clarifications on Skills
Reducing Level Adjustments
Imported Skills (all PCs should at least look through the table of contents in here)
Imported Spells (all spellcasters should read this)

Clarifications on Positive Levels

Positive levels also grant power points in the same way that they as-written grant an extra spell slot (i.e. spell points). Positive levels bestowed on undead act like negative levels and as-such aren’t limited by the undead creature’s nonexistent constitution bonus.

Recommended Errata

Standard Errata

Remember to check the errata for all books that you use in your campaign (if any exist for that source). Luckily, much of the Expanded Psionics Handbook was included in the SRD, so you can refer to the SRD if that’s more convenient for you. Although it’s hard to find, the Complete Psionic book has its own errata.

It’s strongly recommended that you read the official “D&D 3.5 FAQ”. It contains useful clarifications on a number of topics (such as how exactly tower shields operate in-battle). Furthermore, please read as many “Sage Advice” columns from issues of D&D 3.5-era Dragon Magazines as you can.

Weapons

You can add 10 gp to any polearm’s price for the haft be constructed of aluminum-steel alloy (same hardness and weight as wood, but made of metal) and give it the ability to telescope retract down to 2 feet or extended to full length as a move action, provided you have a hand free to manipulate the haft. You can add 20 gp to the polearm’s price to make the haft aluminum-steel alloy and allow it to telescope auto-extend or auto-retract one-handed as a swift action. It takes 1 full round for it to auto-retract once triggered. While partially or completely retracted, a polearm is too unwieldy to be used except as an improvised weapon. You can add both abilities for 30 gp. Add 5 gp to each ability’s price for every 5ft of reach on the polearm. Both abilities automatically come with all masterwork polearms.

Bloodlines racial variant

Bloodline levels don’t count as class levels and grant no benefits to maximum skill ranks or when calculating any character ability based on his class levels, but count as a level adjustment, and thus are halved and can be reduced. You still have to take a bloodline level before you can reduce it, and you still have to take any remaining bloodline levels (which you can then reduce) to retain your bloodline benefits.

Divine Mind class

The healing provided by the “creation” and “natural world” mantles are treated as fast healing 1 for the purposes of the Death And Dying save, except that it stacks with any other fast healing you have in-effect at the time. Keep in mind that you would only include this effect when its timer coincides with a Death And Dying save. The benefit of the “repose” mantle for a spellcaster suppresses the numeric penalties of fatigue and exhaustion, but does not otherwise have any effect on a spellcaster.

Summoning and Creation effects

All effects with the Summoning or Creation subschools/subdisciplines and a duration of “1 round/level” instead has a duration of “2 rounds + 1 round/level”.

Death Ward effect

This spell doesn’t grant immunity, but grants a +10 bonus on the saving throw.

Detect Psionics effect

This power has been rewritten.

Dispel Psionics effect

Change the text of the Dispel Psionics power to remove the line “Dispel psionics can end spell-like effects just as it does powers.” Otherwise this violates Magic-Psionics Opacity.

Protection from Evil effect

This spell and all variants of it don’t grant immunity to mind-affecting effects, but grant a +10 bonus on the saving throw.

Wind Wall effect

Instead of arrows and bolt’s automatically missing, when casting wind wall you must make a caster level check that sets an AC for arrows and bolts that hit the wind wall. If the arrow or bolt’s attack roll beats this AC, they continue to their targets (and have to beat the target’s AC as normal). Non-mundane arrows and bolts ignore this AC and instead make a Will save (success means they continue to their targets).

Jack of All Trades feat

Only allows you to use a skill untrained, and doesn’t give you ranks for the purposes of earning the +3 class skill bonus.

Spell Reflection ACF & Spell Sense feature _

These alternative class features and similar abilities affect both spells and powers.

To reflect spells you must have 1 rank in Knowledge (Arcana), and to reflect powers you must have 1 rank in Knowledge (Psionics), but you must have at least one of those to take the ACF.

Recommended Bans

The following character options are recommended to be banned from player access in all campaigns using this setting on the grounds of them either not fitting the setting or otherwise being silly, overpowered, broken, or useless in the campaign.

Banned Effects

Regardless of whether it’s a spell, power, magical location, friendly NPCs, or another resource, players should not gain access to these kinds of effects or it will break the setting.

Any effect that allows a PC to recall or re-cast a spell is banned (See the Spell Points variant description for why and alternatives).

Many forms of transportation between planes are banned as a result of The Great Seal.

Even before The Great Seal, it was known that traveling from the material plane through a transitive plane and back to the material plane has special limits when the distance traveled relative to the material plane crosses the vacuum of outer space. If you attempt to enter the material plane from a transitive plane and the distance traveled relative to your last location on the material plane would cross more than 2000 miles of outer space, you fail to re-enter the material plane. If the effect used for travel had an instantaneous duration and you originated on the material plane, the effect fails to move you out of the material plane in the first place.

Banned Races

Kender (because #@$% kender !)

Banned Prestige Classes (PrC)

Disciple of Dispater (if you don’t use the House Rules Maginomicon suggests)
