Board Thread:Dark Souls II/@comment-25628189-20150509175543

I recently got SotFS and have about 25 hours in but I have a few questions that I am going to post here because the comment pages are gone and I dont want to look some things up because spoilers. Also I have 250+ hours in Ds1 so Im just new to Ds2 not the series.

1: why are some enemies not respawning even though they shoud be?

2: why cant I use cracked red/blue orbs, and after it says "you are being summoned" it just gives me an error mesage

3: what is the point of the coffin in things betwixt? I know what it does but why?!

4: can I open illusory walls if a message is front of it?

5: the skeletons in Huntsman's Copse get up after they die, do I use a divine weapon or something else?

Sorry for wall of text and probably posting in wrong form.
