Newbee Questions (Bowazon/Javazon, misc.)

[ReloadeD]

Hi just started playing Legacy,
was rough to start, so far i'm playing a +50lvl Poison JavZon

Question 1:
Does weapon dmg apply to Multishot?
- or has it got fixed dmg depending on skill lvl
should i use any bow and just collect +skill gear for dmg scaling?

Question 2:
849
Trick or Treat - is this useful/usable in any way?

Thanks for any rep/help:)
