Undead blood sucking aristocrats who can use really powerful necromancy, conjuration and illusion to do whatever they want with plebs. That is so cool. Other mythic path which I really want is a Geniekind mythic path. Imagine how cool to be a Djin or a Marid.
What would be really cool is the Laser Cleric of Awesometown mythic path. He'd have lasers and be awesome and get all the babes. What's not to like? I'd code it myself if I ever finish reading my Unity for Dummies book.
No, everyone should only use swords in every RPG ever. Like a JRPG, lets remove all races and classes and have only human fighters and swords, everything else is a awesome button and how dare you like to use magic in a high fantasy game or firearms in a game like FNV!!! /sarcasm
As for codding, I never had problems re writing spells in NWN2. The problem is that IDK how to change stuff in mythic paths. Add custom dialog, add custom items, apply a monstrous template in the player, change the model for the companion pet(...) I just can't find in any source code of the mods that I read how to do it. HEre is a quick guide on how to start with modding in Pathfinder games (
