how phantom bullet and sword barrier skill work

[DDD]

i want to know how phantom bullet work I active it but not anything happen only have blue line and how sword barrier work can i use gun while active it (shoot and parry bullet together)

Phantom Bullet inflicts Suppression effect - wider bullet circle (debuff), also weapon dependent to use (i.e. a Pistol will almost never proc the effect, but a Gatling Gun will have a high chance to... snipers are 50/50). Pretty much pointless unless you plan to PvP (dead at the moment, might see more once the DLC drops).

Sword Barrier - pretty much blocks bullets with any sword type (does not work if you switch to a gun)

Like a lot of debuff effects like fire and poison, it 'builds up' on your target until it procs. The more they get hit with it, the more likely it will activate on them.
There are several things that can increase build up speed like accessories and INT.
For Phantom Bullet, best results are to buff yourself with it on your Sniper and change to an SMG. You will spam it off all over the place almost instantly.

The reverse also applies. The greater your debuff resistance, the slower it will build up on you before affecting you and the faster it will cleanse off.
