some questions about lesser giant codex - essence of the giant

i read some info about but i want to be sure.

can anyone explain me how over enchantment skill works?

that's what i know: i should overenchant my skills over 4+ in order to get 1 essence of giants after awakening the character, and then i can trade essences of giants for superior books.
i know there's a table which explain how much essences of giants can i get overenchanting my skills, but my questions are:
1)is the trade 1:1?i mean, i can receive 1 superior codex for 1 essence?
2)there's a limit for essences i can get?
3)even overenchanted passive skills give essences of giants?
4)i should w8 lv85 (before awaken obv) for enchant skills in order to get the best chance?


i bought about 1 hundred less codex cuz i want to overenchant almost 7-8 skill at 10+ so i hope that i didn't waste my money

sry for my english, i hope u'll understand it.ty for answers in advance.

enchant at lvl 84, i think at lvl 85 u cant enchant skills with lesser...

 

you can enchant at 85 with lesser, i've tested it

 

2 essence = 1 super codex
+9 skill = 5 essence
no limit of enchant of skill need an only lucky on percents :d
i never enchant on 85 i do on 84 always
passive skills give essence
i do on my dual i paid 30kk for gc's and i take 110 kk from superior gc's

 

just hunt in it, you 'll have like 50 more lesser gc by the time you are 85

 

i'm a cardinal so i've some problem livling up in that place but ty for tip :d
sociopath ty as well for answering, very exhaustive
