i was looking for something like that as an addition to the assassination plugin i use.
as you welcome suggestions i'll throw in my two pence here:
at first: avoid to "Sneak up, stop sneaking and talk quick enough".
ok it is just a matter of timing and it becomes pretty easy after a short time of practice, but this annoyed me nonetheless.
perhaps pop up a messagebox where you can choose either to attempt pick pocketing or "assassination".
about the assassination itself, i've some ideas:
Backstab (as you described) or Slit throat or whatever you prefer to call it
- depending on stealth, luck and short blade
-- possible results: insta-kill, hurt-then-alert, fail and alert
Knockout (H2H / Non-lethal)
- depending on stealth, luck and hand to hand
-- possible results: knockout (script cast spell drain fatigue and perhaps calm humanoid), fail and alert
Snap neck (H2H / Lethal )
- depending on stealth, luck and hand to hand
-- possible results: insta-kill, fail and alert
and some ideas how even warrior type players will get a slice of the cake:
Knockout (Blunt weapon / Non-lethal)
- depending on stealth, strength, luck and blunt weapon
-- possible results: knockout (same as H2H version but with a bit health dammage), hurt-then-alert, fail and alert
Impale (Long blade)
- depending on stealth, strength, luck and longblade
-- possible results: insta-kill, hurt-then-alert, fail and alert
Impale (Spear)
- depending on stealth, strength, luck and spear
-- possible results: insta-kill, hurt-then-alert, fail and alert
Choke to unconsciousness (H2H / Non-Leathal) an option for Brute-Force-Warrior-Characters with a bit of conscience
- depending on luck, strength and hand to hand / possible without sneaking, even in battle
-- possible results: knockout, fail (and alert, if not already in battle)
Choke to death (H2H / Leathal) an option for Brute-Force-Warrior-Characters with sadistic traits
- depending on luck, strength and hand to hand / possible without sneaking, even in battle
-- possible results: insta-kill, fail (and alert, if not already in battle)
Both choke variants should involve a "choking sequenze" since it doesn't just happen as quick as a wink.
i.e. cast a paralyze spell lasting a few seconds on player and victim. add a possibility to (manually or forced) abort choking if player is attacked by another enemy.
the "warrior type assassinations" involve 4 instead of 3 skill / abilitie dependencies to make it a bit more difficult for them to succeed i those rather stealth based actions.
to enslave a NPC the player must have a slave bracer in inventory and the NPC must be knocked out (either with one of the "assassinations" described above or simply knocked down with not more than 25 % health remaining).
the bracer will be removed from the player inventory and added / force equiped to the NPC.
maybe my next suggestion should be realized in a seperate mod, since it would extend the "assassination & enslave mod" beyond its purpose.
Spoiler
perhaps their "will to serve" might be dependant on how the player treats them.
i.e. as soon as a NPC is enslaved it would be rather difficult to let him do several actions like following (he will refuse several times, perhaps on random / dependant to players luck).
or the order "Stay here" would involve the possibility of the NPC tries to escape if player changes cell. (disable on random / PC Luck)
successfull threatening or "corporal punishment" will increase their will to serve rather quick but will also increase the possibility of a revolt (which should exclude to enslave this NPC again, so the player would have to kill him).
whereas [insert possibility of nice behaviour towards NPC here] will convince them a bit slower but they will become quite pleasant as soon as they accept their fate.
depending on the NPCs willpower there should be even the possibility that they refuse to follow orders at all and might even start fighting the player again regardless the bracer they wear.
