Which monster kills you the most?

Not necessarily the hardest to kill, or the most annoying to kill; Which monster causes the most Grief and experience loss for you?

I most commonly farm on a multishot bowazon, in

Chaos Sanctuary or in the Worldstone Keep.

Bone Fetish and

Willowisp do not give me much trouble in the latter since I keep distance and use

Valkyrie to bait attacks.
Despite the slowness of their projectiles compared to the

Willowisp, Hell Temptress

Succubus fireballs(?) single-handedly account for most of my deaths in WSK.
I have been hard-stuck at level 94 exclusively because of their annoying fireballs. Besides

Slow Missiles, what stat negates these attacks? Fire resistance? Magic resistance? Defense against missiles?

Anyways... what monster kills you the most?

I'm also running a level 94 bowazon, except with the focus on

Freezing Arrow. Whenever I see some

Succubus projectiles coming towards me, my standard reaction is to fire a couple

Arrows in the direction from which they were launched, then just go out of their way. Even if the

Arrows don't kill them all immediately, they chill them enough that they stop firing for a moment, allowing me to approach and finish them off.

Not sure about the damage type of their missiles, some sources say magic, some say physical.

My own deaths since I've entered level 94 have come almost exclusively from Heralds when split farming in a game with 6-7 other players.

Herald gets spawned with Extra Fast or

Teleport and kills me before I can even look. Because I'm stupid, I think I can take him with help gear, so I die a second time and ask for help. This sequence has happened like three times already, you'd think I'd have learned by now. But what would life be without risk?
