Imbuing is getting harder? hmm? Well at the moment I am at 99 imbue...and of course the gains are slowing down ....like any other skill in UO at that level...And we all knew that imbue was one helluva expensive bugger! Unless they changed the rescource value needed to imbue an item nothing in my opinion has changed. well that is my opinion as I didnt have any low end runics to craft anything.
When I first started training the greatest prob was and everyone will agree with me is getting the rescources.
At lower Imbue skill like 40-70 I sent my fighter out to south of yew to farm lichs.. he was carrying a unravel bag and filled it up in about 15 minutes...As the spawn is fast and abundant. Then put it in my house grabbed another bag and ...etc
After I hit 70 Imbue I sent my tamer out to our favorite Scorpion...Miasma..and I did some testing there. I wanted to know if wearing a luck suit has any effect on the items I get when I unravel them.
I did five rounds (filling 5 unravel bags, also looting gold and chests until I couldnt carry more) at miasma which took me about 30-45 minutes to complete. I did that amount of rounds as I reckon the amount of items I pull out should give a good result for statistics
Here are the results for wearing my standard hunt suit with my tamer (he had 172 luck on his suit)
In total my char training imbue (currently at 99) unraveeld a total of 347 armor and weopon pieces. He 494 magic residue and 155 Enhanced Essence. from the 3 chests he got he unraveled out of 36 items 45MR and 20EE.
so now with my best 100 lrc suit with 1,4k of luck
after likewise 5 rounds (amount of time needed was similar) I unraveled 389 armor and weopon pieces to give me 508 MR and 207 EE..I also got 3 chests ...apparently luck has no influence on that..well from the chests I even got less ....36 items gave me 54MR and 13EE...oh and I did get two arties ( a boomstick and quiver of rage)...I didnt even notice them until I finished my last round

i was so concentrated on looting the miasma corpses I didnt even notice.
To compare both results? well when it comes to MR I would say they both fall in the same standard deviation mathematically speaking...well I assume
On the other hand the low luck suit gave with 347 armor pieces a total of 649 MR and EE...with 1,4k of luck I got 389 armor pieces unraveled to a total of 715 MR and EE...*shruggs*
