I can't beat Lagon no matter what I do... I'm just like 4 levels under, didn't know he would become lvl 22 afterwards even though I fought him once at the part when Vena fucks Ophelia and lost. I got the scepter, but it doesn't do jack shit... And he still deals too much damage even though I'm like lvl 18... I have 746 health, 320 SP, 7/8 Warrior, 7/8 Ranger, 103 strength (Rank 38), 75 stamina (Rank 22), 79 dexterity (Rank 17), 50 Intelligence (rank 10), 50 spirit (rank 4), 44 Charisma (rank 2), and Libido aint that important since I don't really use it... and Kia has 507 Health (Rank 2), 567 SP (Rank 3), 35 Strength (Rank 4), 52 Stamina (Rank 10), 67 Dexterity (Rank 18), 102 Intelligence (Rank 34), 52 spirit (Rank 7), 50 Charisma (Rank 8), Acolyte 8/8, Scholar 4/8, and she has some good gear. I got the strongest armor (which I think is Bronze, cause I can't find anything better) and one of the best weapons available in the game and probably the best accessory (Rani's Favor: Silver Necklace) available atm... But still can't do anything to win... I can't even kill atleast 3-4 of his minions since I die by the point I kill 1-3 of them... Isn't the Scepter supposed to do anything at all?
Scepter as I recall is doing it job in second part of fight when your part fight against umber-strong Lagon. In part of showdown when you fight against him and other bunnies speter not doing anything. Also looking at your party setup first I could say...why only MC and Kia is there? I mean you could without much trouble get Terry and Layla too. Well that fight wasn't hard with Terry alone not meantioning Layla (thou I never tried beat him just with 2 member team so it's possible but I assume lvl of party need to be even higher than for 3 member party). Another thing I see you got 2 jobs with 7/8. Getting fully mastery in some of jobs aside 2 not 1 skill gained would give some bonus to hp/sp/lp (in case of warrior would be rank 2 in hp).
So now some more thought on how you can beat him. First you could try look around to get Terry or Layla added to your team (best I would say get both to reach full party). Second if you want beat him with just 2 people need have both of them some kind of aoe skills (currently those skills are only as mastery skills) so that lead to mastering fully few of the jobs (Bruiser 8/8 mastery skill is such aoe and Mage 8/8 mastery skill is another aoe). As for Elementalist this job would be also perfect with having only aoe type skills but....it not yet in current released build (meantioning it in case you went to foe smutosaur and found this job desc there already). I meantioned aoe since with full 4 member party at lvl's you meantioned lagon helpers wouldn;t be any threat to party that could wipe them even with casual attack (after all 4 members mean roughly 2x more often attacking than just 2 members). In case you not wanna play with aoe skills (their use kinda more sp then single target skills anyway and I not sure if your team is rich enouch to buy tons of SP pots and some other helping in fights things like decoy sticks or HP pots) would be using strong single target attacks only on Lagon. Target of fight when you are against him and his children is actualy beat him not them...their could be just some like small bonuses to exp/gold rewards after this part of the fight. As for been able deal much dmg again is better to train jobs that would fit with style of chara: for Kia all magic like jobs, for your MC physical jobs like warrior and bruiser (I see you mostly put point in str so those two jobs when fully mastered should be mostly fit way you spend point on your main chara). Still taking into account you wish to only use MC and Kia...she should try cast all buffs (first should be buff to stamina on herself since if lagon will smash her...it would hurt her A LOT) and MC just...smashing like mad Lagon with all his/her strongest hardest hitting skills.
Only have Kia cause I can't find anyone else to recruit, lol. If you could tell me, I'd be happy, lol. Who's Terry and Layla? I don't think I remember them or if I even encountered them...
Terry can be recruited after finishing the Krawitz humiliation quest for the twins, when you try to leave Riguard after finishing that quest you'll be stopped by Miranda who recruits you into helping her catching a thief, the thief turns out to be Terry who you catch. Afterwards you can go talk to Miranda about his fate and then talk to the twins about getting him a pardon, from there you can go to the jail in the castle grounds to pull him out and recruit him. Layla can be recruited by going to Gwendy's farm after beating Orchid and then coming back a couple days later to pick her up.
Layla was 8/8 on Fighter and Courtesan and was working on Scholar.
I thought that Seductions Jobs are still gated for Layla and the quest hasn't been done yet. Did you just save edit?
To unlock Seduction Jobs for Layla all you have to do is talk to her about Sex then have sex with her after that they are open.
