1: 20-40k, wide range because I've bought similar ones and 20-40k seems fair. (If you're selling I'll buy this)
2: not sure but I'd guess 25kish
3: 4 off health mod 10-20k imo (Interested in buying if you are selling).
4: deep wound duration literally one of the most useless mods 40 to 50kish imo
5: eternals often have armor vs undead, common mod. 20-40k would be my guess
6: 20-40k as well (I'm interested in this if you're selling as well)
7: this thing is pretty old, good collector item but the +7 makes it pretty useless. 50kish imo
8: 4 off health mod get more opinions on it but 30kish imo
9: 20kish
10: 20-30k imo
11: probably 10-20k
12: 10k get more opinions
13: 30kish
14: 10ksih get more opinions
15: merch/5k hard to sell
16: platinum staves can come inscribable req. divine so I doubt this one would go over 5k
get more opinions on most but I hope I helped some
12 - I would think 30kish for collect-ability since people buy anything with vs demons and the HCT is perf 20% & matches req. get more opinions.
13 - Bone staff has always been a nice skin because it dyes very well. black dye on it looks so chilling. I have sold these from 50-100k but its been a while since I sold my last one.
Dunno too much about urgoz shield prices. but with that q and skin i could see it getting 50k easy. again, i'm not an expert on what people would pay for plants, but i'm sure that if it were a perfect +30 it'd get over 100k easy. so for 28 50k sounds right. there's my 2 cents
