i'm still trying to figure this one out. the spectres have a very odd aggro nature. sometimes i can't attack unless it's on the correct "tick"
so it seems when they attack, they're attack isn't counted toward aggro until it hits, or splashes. this allows multiple spectres to jump on you at once. if you time this correctly, you can actually aggro back and forth between 2 monsters, hitting each monster once back and forth until one dies.
just now, i was able to engage in combat with 3 spectres at once, with my char jumping around to each one.
i don't mind this one, but it seems the magic on the spectres are lowered a shit load. i do not have to bring one peice of food for a 167 abberant spectre task.
