Will creatures with transmissible symptoms be able to intelligently apply their poisonous substances onto an object in order to lay a trap, or otherwise weaponize it for biological warfare? For example, thralls could try to coat doors or loose objects with the dust that created them, so anyone who touches that object becomes another thrall. Or, certain sentient civs might be able to capture a forgotten beast and coat their weapons in the toxic blood/dust of the creature to provide an edge in combat.
Also, will there be a way to create temporary pocket dimensions to create bags of holding or similar? I'd like to be able to make a crystal or jar containing soldiers, then throw it at a target and have the dimension in the jar destabilize as the jar shatters, ejecting all of the occupants on top of the target. That, or do the same thing, but fill the jar dimension with lava instead, and make a magical incendiary weapon.
Thirdly, will fleshcrafting and gene manipulation be a possible magic discipline? Will we be able to clone dwarves or summon syndromes as an area-denial weapon?
Lastly, will necromancy be given a more complex skillset, and thus allowing dwarven necromancers to play a greater role in dwarf society? I was hoping to have necromancy be akin to a noble position, requiring a certain quality of room. One could designate the necromancer to raise a corpse, and the raised corpse could have certain skill specializations and respond to the appropriate labors. Better yet, a workshop by the name of Necromancer Altar or similar, where you could order the necro to raise a corpse and give them skills for certain labors. They would be able to perform labors befitting their skillset, but would be unable to improve their skills. If necromancy can be likened to a skill, then a higher necromancer skill level would allow the necromancer to raise corpses with higher skill levels or combinations of skills. Novice necromancers would raise corpses with one Novice level, Adequates could provide undead with 1-2 Adequate skills, and so on. The most proficient or legendary necromancers could raise highly intelligent undead with a wide variety of disciplines. They might even be able to give their undead necromantic skill, for the purposes of delegation or backups should the original necromancer die.
