| guess i'll help a lil >.>
currently lvl80+ gs on ragnarok
here's a list of the promotion tests:
8 - copper hairpin
18 - brass hairpin
28 - silver hairpin
38 - chain gorget
48 - mithril ring (after this rank, sunglasses open up for guild points)
58 - mithril gorget
68 - mithril breast (after this rank, apron opens up for guild points)
78 - torque
88 - jeweled collar (after this rank, furniture opens up for guild points)
dragonhope posted a pretty good ~lvl60 guide. i'll post some altenatives.
18~22 - silver pierce -> it's up to you if you wanna save these to make the lvl14 earrings but i'd just break em (desynth with thunder crys).
22~27 - silver hairpin -> advanced support from 22-24. make and break.
27~31 - silver rings -> save or break them
~35 - +1 stat rings -> if you don't have any saved up, buy the silver rings from lower jeuno jewelry store (or AH i guess if they sell it less) in the shop it's 1250 for silver rings and earring and 4500 for mithril earrings. gems for +1 stat rings are like 1850 kinda pricy so check AH for those gems (usually way cheaper) up to you if you wanna wait and sell these in AH or try your luck and desynth them. NQ/HQ1 is the gem, HQ2 is 1xsilver ingot, and HQ3 is 2xsilver ingot when desynthing. (*note that these npc prices are with crappy jeuno fame)
35~38 - mithril ingots using coins
38~40 - mithril ingots using ores
40~44 - mithril earrings -> rings (for this stage try to just use what you have leftover. earrings are good until 42 and rings are good until 47. it's kinda tedious to mine ore/farm for coins but if you wanna do that too it's fine. it also takes quite some time to sell all those rings through AH unless you got a mule to help you out (and you should be desynthing the earrings unless for some reason they sell more than 8k in your AH) you wanna get to about 44 or so then...)
40~44 - spark lance -> buy the lances when you can if they're in AH. the recipe for lance is 2xsteel ingot 2xash lumber (kinda pricey) but it might sell for less in AH
42~45 - black earring -> if these earrings sell good in your AH then this might be a good alternative to making mithril rings. when you run out of your own earrings remember that the shop in low jeuno sells them. as for the pearl needed, you can get it from desynthing a gigas necklace if you're bonesmith is skilled up or you can get them from sahagins in sea grotto. pearls usually run for 2k on lagnarok.
44~48 - silver bangle. you can get all 3 ingots back if you hit an HQ
48~51 - gold ingots using coins -> grow them or steal them
51~53 - gold ingots using ores -> mine them or buy them (or grow them?)
this is a good time to stop and smell the roses. you can now farm orc masks and desynth them into gold ingots. i never did find the best moon phase for this recipe (my best is 4 in a row on ice day). if you're really patient, you'll save each and every ingot you desynth and use them later. you'll need them from lvl70 on because there's no way to lvl without using gold. you might also wanna think about getting some furniture up in your mog if you haven't done so already. i'd suggest having thunder for 1~48 and fire and earth (maybe wind too) for 48+ (switch furnitures around for your needs).
53~59 - gold rings/hydro claw -> it's up to you which route to take just be sure from 53-56 you do them with advanced support. note that gold rings are good until lvl60
from here on out it's big money so be prepared. skilling up will start to slow down. start paying attention to what days and moon phases give you the most skill.
59~64 - platinum ingots -> using coins are good until 61, ores until 63, nuggets+ore until 64. of course no one should do the ores unless you got oodles of ores laying around. coins are probably scarce so i'd suggest growing your own nuggets and buying an ore here and there or start hitting up pal mines (maybe grow your own ores too if you know the recipe). save these ingots or sell em per your personal needs but you might be using them soon.
and i'm gonna stop there. hope this post was useful <.< if you got any questions (for those on lagnarok) send me a /t
*edit added in some alternatives for 40~45 range  don't be jealous
actually be jealous, just don't bother me lol |
