What should I do with my other 2 slots?

I got 2 more build slots, just wondering if anyone has any ideas for what I should do with them.

I'm enjoying my tank crab, but I also want something with some good DPS. Wondering about making a Huntsman with some bane powers or another crab who is more DPS oriented.

Make a Bane with some Huntsman powers. A Toxic Bane. <3

Fine, but you have to coach me on how to be awesome like you. Right?

* Venom Grenade is -20% Resistance to all but Toxic, which is -40%. It favors a build heavy in Toxic damage, and is a pretty nice AoE attack in its own right. It's damage-over-time, so things won't die as soon as it hits them, but it's got an interesting side-effect that you can boost its damage with other debuffs after the fact.

* Arctic Breath from Leviathan Mastery is another -15% Resistance to everything. On top of that, it's -11.25% Defense to all; -30% Speed and Recharge; periodic knockdown; and--you guessed it--a pretty nice AoE attack in its own right (Cold DoT). Its speed and attack debuffs will reduce incoming damage after the alpha volley.

* Bile Spray, also from Leviathan mastery, is a cone of the same size and shape as Arctic Breath and deals pure Toxic damage over time. Arctic Breath was going to be a replacement for Bile Spray in Issue 13, but that decision was repealed and now we get both. After the two debuff AoEs are cast, this power will be 55% more effective.

* Build Up will increase the damage from all three AoEs in addition to making them more likely to hit every target they trigger a to-hit roll on. It won't boost the debuff portions, but it lasts long enough to get all three attacks off and all the DoT ticks from the powers are boosted by it.

* All of the mace melee attacks deal a Toxic DoT (100% chance) in addition to their smashing damage. It makes for an eccentric bludgeoning weapon that really benefits from the -Resistance debuffs already applied to the enemy.

* You can peg tougher targets with Surveillance for an additional -20% Resistance to all and -15% Defense to all. It doesn't aggro, so you can butter them up before launching the AoE debuffs at them.

* Poisonous Ray is some outright silly-high DoT. It's the #1 hardest-hitting Toxic attack available to player characters (Venom Grenade's #3 and Bile Spray's #5), doing a good 105.66 damage over 2.10s. You can debuff an enemy to -75% Resistance to Toxic, which gives this power 184.90 damage per activation without even Enhancing it.

* The ranged mace attacks have some good DPS, but they're of the low-damage-fast-recharge variety. If you're going to be casting debuffs, redrawing weapons and spewing shark breath, you might want to skip them on merit of having an incompatible attack chain. Frag Grenade's still a nice attack that can be launched alongside Venom Grenade, but then you have knockback to deal with (although there is Wide Area Web Grenade for that)... Mix and match to see what works best for you.

* Alphas are a dime a dozen, but Cardiac works really well for Endurance management (freeing up slots for other stuff), and Total Core boosts range by 20% as well, which is very useful for the AoEs (the cones in particular) and Poisonous Ray, which normally has a depressingly-short range.

* The Degenerative Interface has some options for dealing Toxic DoT through all attacks. You can get up to a 75% chance that way, which works wonderfully with the AoEs. With a Radial tier-4, you'll have a 25% chance for -3.5% Max HP on top of that. Otherwise, I'd suggest Total Radial tier-3 for the 75% damage proc by itself.

* Judgement's your call, and nothing's particularly Toxicy. I went for Cryonic and made it green. (-:

* Lore's a matter of preference, but I took Robotic Drones since they're small and inhuman. Turns out they've got the D.U.S.T. plasma blasts, which are all -Regen.

* As far as Destiny is concerned, Barrier will probably be the most helpful on top of Maneuvers and Combat Training: Defensive. I can see Rebirth being preferred in some situations, but Ageless, Clarion and Incandescence don't do as much for the Toxic build.
