The unique Slayer form (exclusive to Dark Urge) has a few issues;
By default, the Slayer'sRelentless Lungeis incorrectly assigned as its Main Attack (the main attack is supposed to be Slay, as Relentless Lunge is just a once-per-turn bonus action)
If Dark Urge becomes a Vampire, the Slayer'sVampire Bitewill neither show up nor stay on the main hotbar if dragged (to use this ability the player has to specifically go into Bonus Action(s) section of the hotbar)
If Dark Urge becomes a Vampire, the Slayer'sVampire Bitewill also not have an animation when biting people (could use the same animation Sumptuous Blood Bath uses)
*As can be seen the Slayer is using the wrong ability as its main attack, the Vampire Bite refuses to show on the main hotbar, and the bite itself has no animation when used*
