Personally I do not max out Attaque au fer and leave it at 1 point reason being that the hit box is crap and the dmg wasnt too good,I put 1 point into this skill.
skill:
Lunge-1- actually quite useless, filler skill, I would add this 1 point to another skill when next rank reset came reason being that you are busy doing other things so you barely use this filler skill.
sept etoiles-15- one of the main dmg skill, max it out
Attaque coquille-4: debuff, deal more dmg with pierce dmg, but I heavily suspect this one is bugged because I dont feel much difference. 8 sec cd, at lvl 4= 8 sec debuff, so keep at lvl 4 is enough.
Flacoonade/ Esquive Toucher: completely useless after fencer c3 is out, flacoonade is slash atk and esquive toucher has one of the worst hit box and high cd.
Attaque Composee - 10 nothing outstanding, a low cd medicore dmg skill, but it is pierce atk so>flacoonade.
Preparation - 1 double the next pierce atk dmg you do, a skill help you burst like a god, geared fencer with this skill easily hit capped dmg 555555 if crit, but only 1 point is needed because add more just increase the block during the skill duration, note: do not auto atk after the skill it will consume the effect(rapier auto= pierce), but you can do other skill that is not pierce element.
Balestra Fente - 5 reduce crit resist on enemy, max it out because it is the only skill that can consider to be an aoe…well, crappy aoe is better than nothing.
Attaque au Fer - 1 filler dmg skill, 1 is enough.
Flash - 5 your highest dmg skill
Epee Garde - 5 MOST IMPORTANT SKILL FOR FENCER, ACTIVATES THIS SKILL AND IF YOU CRIT, YOU HIT LIKE A GOD, I HIT LIKE 150K WHEN CRIT WITH 315 BLUE WEAPON WITH PREPARATION USING Balestra Fente. IT INCREASES YOU CRIT DMG BY 50%(only applies to pierce atk). But on the negative side, if you crit rate are low, well you are screwed.
Edit: the guy’s video above me is a great example of a geared fencer, im still trying to get my Black horn T T
