No.. You can do it without transcending.. Blacksmith is fine.. and you're adequately leveled to mob efficiently there.. And blacksmith/whitesmith is the best class in Niff since you have the greedskill which efficiently lets you take the loot and having the biggest weight limit out of all the classes because of your cart..
Top Headgear: Kaho or soul ring.. or any high def headgear
Mid headgear: Bloody Knight Carded AWE/EWE for +27 str total

Also, if you have a sage or prof- Fire endow your blacksmith which lasts for like 30 min and you'll get extra damage from the fire elemental .. You will dmg more from 125%(quve) to 200% (dullahan).
Stats
try to get as much str as you can.. So you can hit hard and fast
with dbss mace, you can use berserk pot and add enough agi to achieve 190 aspd.
High vit.. like +99 for survivavility
no int.. with dbss mace
Dex-I'm not exactly sure since I haven't been in niff in years but not alot.. Just enough to hit the monsters there
Luk- Nah.. Don't need it.. Spend it on str.
If you have any more question or what not.. Feel free to ask me.. Oh and also, You need a priest that knows the map to niffheim to warp you there.. Either you have your own priest to warp you there or either have a friend warp you there or pay them for the blue gemstone.. It would only be like 1k
