Trouble taking down Ilfrit

[-DMR-]

Well, I have 3 other classes, none of which are high enough as archanist.

However, I do help as much as possible with bringing the nail down, but despite that, it would be already too late, as Ilfrits most powerful attack is made.

I will continue until I get it right and no one else drops out.

Are you casting your DoTs on the nail and ordering Emerald Carbuncle to attack it aswell? I mean, some new arcanists tend to think Bio and Miasma are not powerful enough compared to bigger numbers coming from Ruin (which is plainly wrong) and forget to change Carbuncle's target from Ifrit to the nail, leaving it with Ifrit and casting just Ruin on the nail.
If you're keeping DoTs up on the nail (and Emerald Carbuncle attacking it aswell) while casting Ruin, the issue does not rely on you but on the rest of the party members you've been playing with instead.
