As said, have not touched these items for a LOONG time, if i see this now, sure could be better by any means but well, same “not so good” items are fine ATM, not a priority to change, if i think about it more i would say it would be best choice to produce UNIQUE items for these bosses aswell… also for ONB’s, but we will see when the time is up for this;
2nd Two-Handed Sword i do not think its bad at all for maybe Oathkeeper/WD…?
Book of Eden, yes, seems bit underpowered, true, especially the damage statmods, i do not remember if i have tested that itemskill, really LONG ago this has been done ;D
→ never had an issue on this, i must admit 
for the most time i simply take bounties everywhere i go, as you can do even alot more via this integrated mod this shall not be a problem: “[Mod] [Release] Bounties Unlocked”; what do you mean by “should not apply to Pet build” mate?
