These would be regular research values but the order is different. You get a spell then a matching room for the spell (the opposite of vanilla DK1) also you get Bridge then Workshop then Guard Post. Order being reversed. This makes it so you can start building traps earlier.
Sight
Bridge Room
Obey
Workshop Room
Call to Arms
Guard Post Room
Hold Audience
Barracks Room
Speed
Prison Room
Cave In - the idea is to get this damaging spell before lightning since lighting is pretty OP
Torture Room
The following are x2 longer research. This makes it so you get most of these mid - late game. Whoever gets to scavenger / temple can really do some damage. Plus heal and conceal + possess to explore enemy tunnels while invisible. Also having graveyard this late means fewer vampires.
Heal
Temple Room
Conceal
Graveyard Room
Protect
Scavenger Room
And finally x10 longer research. This makes it so you get these spells only late game if ever. Destroy Walls is pretty broken and you will barely get that far.
Disease
Chicken
Lightning - problem with lighting is that is instant damage that you can't avoid. this makes it really OP . you can install kill most level 1 imps anywhere on the map which is why should not be available so early in the game
Armageddon
Destroy Walls
With this your research room will be very valuable all the way to late game slowly researching more and more powerful rooms and spells.
What do you think?
EDIT: On second thought I think swapping Concela with Cave-In would make more sense making Conceal available earlier for normal research time and Cave-In x2 longer research before Graveyard.
EDIT2: After further playtesting I conclude this does not make the game more fun but rather makes the game last longer. If longer game = more fun for you then by all means go ahead and do this :3
