Thanks for the comments :) Yes you're right with multishot a single target can only be hit by 1 arrow. This is a change I made because the skill simply became too OP otherwise.
Since that change - might make sense to up the attack speed of bows a bit.
Yes there should be more than one graveyard - I expect it will work so that visiting regions with a graveyard binds you to it. But death is also supposed to be at least a little bit of an inconvenience :)
