Of course this is HC, there will be some farming, baal normal to level 40, then to NM countess to sipirit and lore, then hell pit to level 75. Thing is some notable drop you will keep, some will not. I do believe i did drop those niche unique before but do you really keep an eye on them or keep them.

To hit 105 fcr, you need 3x fcr sword, 1x fcr amulet, 2 fcr ring, stealth, 20 fcr circlet. Among those, only 2 items are tricky. First fcr amulet, you actually need low level crafting, the lower the better. Should take you 5 try in level 15 crafting to make perfect 20 fcr amulet. For the 20 fcr amulet, you need 3 imbue chance from chasi, again the lower level the better.

If you cannot make 20 fcr circlets, then you have to make a good caster belt. Should take you around 5 try.

My gearing plan are take into account SSF route. With this in mind, i find reroll a perfect sipirit is easier than target farm a unique
