House rules are defined as a set of rules that add to, remove from and/or modify the core rules of a given gaming system. These rules are normally exacted by a Game Master (GM), though tend to also be adopted by groups of players. House rules are typically created by Game Masters because they do not particularly care for the mechanics or explanations provided by specific core rules, or if the core rules do not provide certain mechanics used in a game. House rules are not meant to replace core rules but simply enhance them to provide a better experience for all involved with a game.
The house rules of Mægwen offer enhancements to the Dungeons & Dragons 3.5 core system purely to make playing within the campaign world more enjoyable. Moreover, these rules alter a number of class rules insomuch that playing without them could delude the campaign setting. It is highly recommended that these rules are maintained because they were created specifically for the setting. Running an adventure or campaign without the use of these rules may create a significant void in the overall experience.
Mægwen house rules modify the following D&D core rule categories:
Class modifications may or may not occur depending on the continent. For the sake of organization, any modifications to core classes and additions of new ones are found in the designated continent's section under "Updated Classes." Even classes that are nonexistent in a particular setting (that is, particular continent) will appear in the list with an explanation as to why. All other rules found in this section are universal and occur regardless of setting.
This campaign world was designed strictly for the d20 system with D&D 3.5 as a backbone. Because D&D 4th Edition adheres to the d20 core concepts, these rules may be modified fairly easily, though significant changes made leading to D&D 4th Ed. may cause some problems. It is up to the individual GM to rectify these potential problems without sacrificing the integrity of the Mægwen campaign world.
