my resurrection system idea. units are boxed when a troll dies he/she will become a bodyless spirit. (shade) then he/she has 2 options: to be r

You should include a whole halluciogenic plant culture to them, like in the book The Teachings of Don Juan.
Maybe a shaman class of troll can travel to the ethereal world with the help of some allied hallucinogenic plant and find a spirit to become its eternal servant, which will be able to possess others that are under an abnormal reality state and perform deeds to that shaman. Download I-doser tracks to make players high, too.

well i have had the idea of introducing drugs to this game. it would be quite logical. e.g. some ancient central american cultures administered the leaves of coca plant quite often and it normal, even traditional (cocaine is made from it nowadays).
but it might not be ethical to put that into the game. should have a poll for it
(ganja: yes [x] no [ ])

I also have an idea - if all of the characters players will lead them to a particular outcome. First, there will be no classes and ranks, all are equal. Only later did the actions of each will depend on their fate. For example, if a troll will die at night in the cemetery between 00:00 and 01:00 that he would perform voodoo rites and rise again, but as a zombie filled with energy voodoo. Such options rebirth / evolution can think of very many. It depends only on the imagination. The main thing to avoid the players did not know how rebirth / evolution. It will be very interesting and intriguing. Of course he should observe the logical aspects.

I'm for Ganja, the closer to the reality of the game will be better
