Several bandits in a cave, you kill one, a wandering bandit (with appropriate lighting/carried light source) comes by the corpse that you didn't dispose of.
Is it possible to have that bandit forced into a frenzy, weapon at the ready, aggressively looking for the PC? Possibly alert the others, and have them in a frenzy?
Surely they'd notice if so-and-so was missing, or lying dead right in front of them...
It might be possible to do a within line of sight type script on them, though I honestly don't know how to go about it. I know that there are line of sight scripts in a few mods, though they are typically buggy......that being said however, I am sure its possible, if not practical, Fliggerty needs summoned as MWSE may be more useful than morrowind's own ancient scripting engine. Come forth yee great scripting genie, for thine gifts are much appreciated and respected!!!!!!!!
That should do it, if not, we need to get Peachykeen in here to do the summoning ritual, he's vastly more experienced and fruitful in his summoning rituals than I.
Edit: Fixed gender misconception, my apologies PK, and thank you E-W for the correction!
