Notrium version 1.3 includes several new features, among them are weapon and item classes, which allow you through the player_races.dat file to limit what a race can use.
The Psionic start with several Psionic Tokens which represent a discipline, they are used to access the deeper recesses of the Psionic's mind which are essentially dungeons or dreamscapes where the Psionic obtains new Tokens which allow it new abilities. Only the Psionic starts with the Tokens, therefore only the Psionic can access the special areas which take place in its mind.
So you may spend a considerable amount of time conquering each dreamscape so that your Psionic becomes more able and of course powerful.
Version 1.3 is shaping up quite nicely and I strongly believe many modders will be pleased with the host of new options available to them, not to mention the flexibility offered in their execution. Weapons, Items and Plot Objects are more or less standardized, using the same effect and condition system. Yes you heard me right. You can now make some very bizarre weapons indeed. Dare you make a creature spawning, ether eating contraption !? Well you can in 1.3 and much more !
It will be key to the ambitious modder to more or less memorize what each effect does as they are commonly shared amongst the files.
Once you decide upon what you want to happen, you than choose what will be the source. Should it be used at will with a left click as a weapon ? Allowing for things not possible before, like a potion that must be selected like a weapon, than used to restore vital health or whatever your creative mind desires. Perhaps you'd prefer to have a secret ambush triggered as a player nears a certain object, than you would use a Plot Object and spawn a creature when they approach the object. Of course the old traditional route of executing an effect from the inventory is still very viable and lets you allow the player to be safe as they use the item, yet now unlike before you can have effects cued to different keys and of course have multiple effects instead of just one.
Well that is enough for now Enjoy
I'll be happy to answer any Mod specific questions in the appropriate thread.
