You can't get quite the exact same stats with imbuing. What you can get easily, which would be comparable in both item value and usefulness, would be to make a woodland gorget, then PoF to 255, then imbue, then enhance with bloodwood. You won't get the HCI, but you will get HPR 2 and one other property of your choice instead. If you use 2 imbues for resists (physical and cold, making a lot of pieces till you get some that have the majority of the exc bonus in poison and energy), and the other 3 for stats, you would get:
Hit point regen 2 from the bloodwood
5 hit points
1 other stat of your choice. Most people would choose LMC.
Phys 23
Fire 20
Cold 18
Poison 17
Energy 16
mage armor
You can adjust the resists somewhat according to what you need for your suit. In most cases, if you're making a whole bloodwood suit, you will only need to use 1 imbue per piece to get all 70s resists; that way, you actually have 2 extra stats of your choice to use instead of 1. You could easily have something like:
HPR2
5 hp
LMC 7
MR2
Phys 10
Fire 20
Cold 18
Poison 17
Energy 16
Mage armor
A couple of other notes: HCI is capped at 45%. Most of us already have HCI on our jewelry, and quite a few have HCI on our shields, either from old shields before they quit putting the property on them, or from museum of vesper replicas (although the -1 casting makes those less attractive). There is an old 15 HCI/15 DCI/FC1 shield for sale in Luna Atlantic right now.
If you really needed the HCI instead of HPR, you could keep making pieces and enhancing with heartwood until you got the HCI property, but you would go through so many bottles of PoF that there wouldn't be a bottle left on the whole shard. Also, you wouldn't get the +8 fire resist that enhancing with Bloodwood gives, and you wouldn't get the HPR 2.
You will have about a 10% chance of success enhancing. That means you will need to make 10 pieces, if you have average luck. If you want the finished item to have maximum durability of 255, you will probably need 20 bottles of PoF at 100k per bottle, total 2 million. Imbuing 10 pieces of armor with the mage armor property will require 200 pieces of abyssal cloth @500k for 10, total 5 million. For the resists, any character, even a crafter, can get 10 boura pelts in like 5 minutes, so I wouldn't even count those as worth counting. LJs drop luminescent fungi for the hit points on the ground at the banks, so it's also about worthless. The rest of the ingredients are fairly cheap, unless you decide to use the extra imbue to put something like mana regen 2 or LMC on the piece. If you decide to only use 1 imbue for resists, and put both LMC and MR2 on the piece, its cost will double. I would guess that you will spend about 10 million total making a piece that is comparable to the replica, 15 million if you imbue LMC instead of a cheap property for the 1 extra stat, or maybe 25 million if you only use 1 imbue for resists and sink the points into both MR2 and LMC.
Note: Like imbued items, you can't use PoF on replicas. Most of the replicas have durability of 150, and your finished piece will have durability of 255. If you just use PoF to make the total durability 150, the same as the replica that you're wanting to simulate, you'll save about a million.
