i unno how much it would help but i can tell you basically what each persons continuation quests are
Fef(The Monk) - Style based map completion
~1 = 65% style
~2-3 = 70% style
~4-5 = 75% style
~6-12 = 80% style
{Thats minimum style, pass quest 1 with 72% style thats great, you still win}
Kiri(The Gunner Girl) - Rank based map completion
~1-3 = C Rank
~4 = B Rank
~5-7 = A Rank
~8-10 = S Rank
~11-12 = SS Rank
{p.s. im not sure but every translator i read seems to pop out "more than" or "over" said rank so ill do some testing and see if you need that rank or higher or above that rank}
G.S.D(The Ghostknight) - Hit based map completion
~1 = 10-Hit
~2-3 = 11-Hit
~4-5 = 13-Hit
~6-7 = 14-Hit
~8 = 16-Hit
~9 = 18-Hit
~10 = 20-Hit
~11 = 22-Hit
~12 = 24-Hit
{for example if youre doing quest 9 finish with 0-18 hits done to you and you win; however it MAY be 0-17, more testing is required}
Kagon(The DarkElf[m]) - Technique based map completion
~1-2 = 70% Technique
~3-12 = 80% Technique
{or you know, if youre crazy you can always get more
}
Sushia(The Bartender) - Item Gathering Repetition Quests
~2 Berry of Marijin - 1..Beer?
~5 Berry of Marijin - 5..Beer? lol
~2 Grapes - 1..Wine?
~5 Grapes - 3..Wine?
{I'll be posting these later, i need to get the ingame name for some items because i sorta forgot ~_~,also not sure if its sushia or Susia, ill try to look more into it}
uhh ya hope i helped, also the jar head guys quests will always be time trial rounds in maps, i do them when i can because i love opening jars, never know what youll get hope i helped some people =P, if people want i'll also post the lvl requirements for each of them.
So happy i got to contribute something
even if its just minor.
edit: added the 2repetition quest i can do forgot to look at the beer/wine/grape name before i closed dnf too lazy to open again, if theres higher lvl ones and you wanna state them feel free; ill also update it with [item images,quest rewards,lvl req] if people ask, otherwise i wont cuz its too much work if people dont want it
