So for those who don't know what Oblivion will-o-wisps are, they are extremely annoying (and generally difficult to take down for the unprepared) spirit-like creatures who can turn invisible, drain health (like lifesteal with spells), and are immune to physical damage.
Well anyways, my mid-level high elf caster happened to draw the attention of a wild one one day, and I literally didn't notice it following me until I met a nearby guard charging towards me. I drew out my enchanted sword and got my most powerful destruction spell ready, but just before I was going to attack, the guard ran past me and started hacking at the air.
At first I was like... O.o guard AI glitch?
But then I saw that wisp appear and I understood.
Rather than help the guard take on the wisp, I found this situation rather amusing, so I just stood at the side watching.
The wisp killed the guard without taking so much as a scratch of damage (being physical immune spirits), so I thought, hey, maybe I could cause a bit of mischief with it
.
I lured the wisp to the outskirts of Skingrad (a nearby city) and just watched as 3-4 people flailed futilely at it with axes, clubs, and fists. A few nearby guards tried shooting the thing with arrows, but that of course did nothing as well.
Eventually, all that was left was a pile of bodies (which I looted for gold) and the wisp, still levitating about.
I decided to shoot the wisp down with a few fireballs (they aren't immune to magic), but I'm just kinda thinking, what if I decided to let it go in the city itself? Would it be able to take out half the city before someone gets smart enough to shoot it down with spells? Why don't they have any magic casting guards around? I mean in theory, two or three wild wisps could basically take over all the cities in the game if their AI allowed them to.
Just a thought.
