Just to be clear on my end. Zek or FV weren't mentioned. Either of which would of made including No Trade stuff viable, but asked for tradeable stuff to start with, then mentioned No Trade in the example list. I could have, and would have included some other ideas (Mostly Ssraeshza Temple mobs, as they're mostly easy to get Alts to. Just set off the traps on the higher level toons then move the alts through, other than the Emperor is a little trickier and more involved getting the key).
The tradeable made me think, either easy / quick to buy, or sell-able, and thought I should mention how farming takes forever. Just searching the bazaar may take quite a while in and of itself. If they want to do it, just to see what they can do, or want to sell the stuff or whatever else, is fine. Just wanted to make sure they knew it would take some time, and alot of time with No Trade drops. The No Trade quested boots takes a bit of time, but not too long, especially if you happen to remember to save the hides whenever you are hunting there anyway. I assumed that was the plan from the OP.
Zek of course, being twinked out is almost a necessity, and FV No Trade gear is mostly trade-able anyway, so you can buy it, and not spend hours each try to farm one or possibly two pieces that will fit your class.
The best time would have been when Trio jewelry settings didn't have a required / recommended level when they first came out, and you could of had 3200+ HP and 420+ AC just from jewelry at first level. Add in some 100+ HP 1st level items, get some GM MGBs without level restrictions and you could of easily been over 10K HP at 1st level. I couldn't find them, but I thought there were some 50hp augs, non-Lore, from a limited time, special event quest, that you may have been able to get at 1st level, or a higher level, then sacrificed down to 1st level, that went in most slots, that could of gotten another 500-700 in HPs. Anyway, that seemed like the ultimate time to get the most twinked out 1st level.
I'm rambling on again. Got lost in the side-track looking for those strange 50hp augs. I should have posted about them when I found them, so I had it written down some where. And the main thing is, I just wanted to be sure they were aware of how long such twinking will take compared time to level past it. 'Cause if that was the reason for the twinking, it's not really necessary, unless as Vinney said, you're on Zek.
