The size of our mod, is partly because we havent cleaned up files not needed, but also because we are modding a mod. Ice and fire is like a mod to normal WoTn.
There are modded until greenwort in text and quests, but the skill system, acrimaldo etc continues. You only have a few open skills at start, each time you level up you can get random skills which you then can develop. No prereq. for skills. Info is at top of this thread... reduced the amount of undead and made random enemies instead. Companion is like the pet/companion in red sand, but you choose between 3 which is random of 7 different ones!! The rank system is the same for the units, like in wotn or red sand, but goes to lvl25. Wotn must have copied system from REd Sand...
