@nvmvoidrayz Let's call it lv45 for the sake of this.

Ok, so a lv59/45 Te/Fi Female Newman has a base HP of 455 (ie. no Unit bonuses, no HP Up Skills, no HP Augments). If you have minimal HP Augments or Unit stats, then your HP looks to be fine. Even with a full powered Deband Toughness active, that would bump you up to only around 570HP.

Can you please give your subclass and its level.

@Shayuna The Photon Sphere Exchange Shop. In the Shopping Plaza. Up the stairs opposite the Salon.

@Shayuna Eventually, you can use them to get Ultimate Boosters which are needed for some potential unlocks on some 14* Weapons, as well as for trades for some 15* Weapons.

For now, you can trade them in for the 11* Weapons in the shop and turn those into Excubes.

@pixiebitten4 Fighter is a great sub, especially if you are primarily using Jet Boots since you can take advantage of Fighter's Chaser Skills very easily. It is overall squishier than using Hunter as your sub, but you can potentially hit harder. Plus it is easier to go Bo/Fi -> Bo/Ph than Bo/Hu -> Bo/Ph since you won't get accustomed to all the survivability Skills and instead learn to rely on your i-frames and dodges a bit more.

Bumping, because, why not?

Maintenance would have been last night.

@xChocoQ Quick weapon swapping is only possible with a keyboard. Each weapon slot is assigned to a NumPad number, so you don't need to open the weapon select wheel.

I see you are missing something big from your Tree if this is accurate: Stance Skills. One of the biggest reasons you are having issues is also likely that you are not hitting hard enough and thus enemies aren't dying fast enough, giving them more opportunity to attack you.

Common practice is to invest in your Stance Skills as soon as possible since they are the biggest source of damage multipliers.

It only works for Units.
