I sense the Recon ability concept in the form of a weapon some day.

I was quoting from the Poison status page itself. Perhaps that is why you didn't see it. The Venom Veiler is arguably inferior to the "main" vaporizer series. That is because Ash of Agni causes constant damage (useful when surrounded by a giant mob), Shivermist Buster leaves them vulnerable to attack and freezes them in place, and Voltaic Tempest both does damage and can possibly interrupt their attacks. With Venom Veiler, you have to do most of the damage yourself by attacking, which even though the damage done to you is reduced, can still be quite painful. It is however, when working with a good team (and possibly when used in conjunction with the other mentioned bombs) very useful for taking the enemy down faster and can be a wonderful contribution to your team in Arenas and Danger Rooms. Just remember it only inflicts "Minor" poison, so you will have to constantly use it to keep them poisoned. Avoid the Stagger Storm though. Minor stun really isn't worth much because it only lasts for a couple seconds.

Voltaic tempest works like the usual status bombs. Explodes with a small amount of damage, and spreads a large shock status cloud. The Electron Vortex works like the Graviton vortex: it draws in enemies within range, holds them in the center for a few seconds, then explodes dealing a small amount of damage with a large knockback.

The EV is generally for grouping enemies, to be used in combination with guns or swords for dps. The VT is used to reliably spread shock status over a wide area.

"With Venom Veiler, you have to do most of the damage yourself by attacking, which even though the damage done to you is reduced, can still be quite painful."
Actually, when you use it in a room with menders/silkwings they will kill the enemies for you as it reverses the effects of healing - instead of healing they will damage them. I cleared whole rooms with just Toxic Atomizer, its insane what the bomb does when there is healers around.
