-X- will hazard another guess, since his previous one was brutally cut down in it's prime.
-X-'s Plan B is that there is something resembling the "target and space bar" system of Avernums 1-3. -X- is probably wrong, Again, but he has a Plan C, too.
-X-'s Plan C is that there is a "probe" spell or skill. For example, you find a new creation. You do not know what this creation is. You cast a spell, "Essence Sight" or something that tells you the creations abilities, resistances, method of attack, etc. This is also implementable in skill form, i.e. a "Shaper Knowledge" skill. If you have "X" amount of this skill, more creation descriptions become available, and new abilities for your own creations are discovered. nothing big, like at level 10 Shaper Knowledge you discover that your fyora can take down a Battle Gamma, but tiny stuff, like a vlish can weaken an opponents mental resistance, making more vulnerable to Daze(By about 10%).
-X- also suspects that enemy creations will have the spell/skill as well. They will be able to see that your magic and acid resistances are 127%, and will stop using Searer, and bite you.
-X- hopes that he is at least partially right on at least one of these counts, and if not they will at least be vaguely wanted but not added due to the fact that the coding required for reducing and increasing resistances has not been seen in this world. -X- thinks that they are good ideas, even if they will ineveitably wither, die, and be forgotten.
