Marine slotting, generally

[Forager]

Am I wrong or does this set not require a lot of enhancements? I'm looking for general advice, experiences and best practices as opposed to builds.

 

I started up an Ice/Marine corruptor. The secondary slotting escapes me. How am I supposed to be slotting these things generally? I have no experience with the set and little experience with buff/debuff sets generally.

 

I'm not having end issues, I'm not waiting on anything to recharge and a lot of it is +/- damage anyway... so it all seemed to work well single slotted.

1. Shoal Rush

 

Generally a skip, as of the two must-pick powers it has less slotting options and end-game utility.

 

2. Soothing Wave

 

You can slot this with a healing set, or just place the Preventive Medicine proc in it:

 

 

3. Toroidal Bubble

 

This is where you slot your resistance sets. 3pc Gladiator for the KB protection and defense, Steadfast Protection for defense, and an EndMod IO for endurance:

 

 

4. Whitecap

 

As many procs as you can fit while maintaining 95% chance to hit +3 mobs. -Res, purple damage proc, and Force Feedback procs are the highest priority. A high-end build should aim to reach 95% accuracy without any slotting (Kismet IO and Tactics helps):

 

 

5. Tide Pool

 

Either an Endurance Reduction IO or a Slow Mod IO. Endurance Reduction will be better while leveling, but you don't have a way to keep stuff from running away as a Corr so the slow mod can help when soloing stuff once your build is fleshed out:

 

6. Brine

 

Either an Acc/Heal Hami or just a straight-up +5 Heal IO. While leveling you do want Accuracy, but since we already aim to get 95% chance to hit without slotting, you can just slot a Heal IO in there once the build is done:

 

 

7. Shifting Tides

 

This is the most interesting slotting. Since the power passively affects both enemies and allies, the ATO proc gives you and your team a heal and endurance pretty much every 10s, and the Gauss proc gives you a build-up at a similar interval. You can split the ATO set by 3-slotting to get more recharge, or you can get more accuracy out of 4-slotting it to help with fully-proccing whitecap:

 

 

 

 

8. Barrier Reef

 

We always want the LotG IO here. Some people like to slot some defense here, but since its defense is unreliable my preferred slotting is to slot a 5-piece Panacea for the recharge and absorb. Panacea proc can proc on allies in this power:

 

 

 

9. Power of the Depths

 

You always want the 5-piece Panacea here. As for the 6th slot, the EndMod/Rech hami/d-sync or a simple +5 EndMod IO (if you +5 all rech pieces):

 

 

That's pretty much it, slotting for procs and sets.

Thanks so much for this. Other than the panacea proc in barrier reef, this is very different from what I have.

I’d argue you probably want more slots in Brine and Soothing Wave.  I’m also not sure what you mean by Barrier Reef’s defense being “unreliable”.  It’s exactly as reliable as the Absorb.

I may be in the minority, but I happen to like Shoal Rush. The slow stacks with Tide Pool and it activates the Tide Pool Frenzy. You can also throw an Achilles' Heel proc in it.

 

I've done some experimenting with Brine and strongly endorse adding slots (I slot 5x Touch of the Nictus). While the -res doesn't stack, the -hp does.  When used in range of Shifting Tides, the recharge is cut dramatically and you can spam the heck out of it. I pretty much only use it on hard targets, but it really shreds AVs (which have no resistance to hp debuffs).

 

I tried the Gaussian %bu proc in Shifting Tides and found it didn't fire much. I've currently got it 3-slotted with dmg/end HOs (the endurance cost is significant).

Soothing Wave with a heal set is an option like i said, but i find that i never use it. As a sidenote i do 6-slot it on my defender builds as i feel more obligated to support there.

 

Going with 2 or 3 slots on brine is solid (touch of the nictus), i probably should have mentioned that as an option. I just don't use it that often outside of as an opener against AV's or against Hami. +5 Heal IO does the trick for that.

 

To elaborate on barrier reef, you can't get a recharge set bonus if you invest in both, and defense is more important to have at the start of the fight due to debuffs coming your way, while absorb works just as fine if it arrives a bit late to the party.

@Uun

Regarding Brine spam, it's important to remember these things:

 

1. The HP debuff is less impactful the lower %HP your target has, meaning that a target with 50000/100000 HP will have their max HP reduced by 500 but their current HP reduced by 250.

 

2. The HP debuff, while not impacted by AV resists, is also not impacted by resistance debuffs on that AV or damage buffs on yourself, while your attacks are. So against something like Hami with massive resists it's valid to spam, but most AV's do not have that much resistance and fall to the negatives a lot more often.

 

3. Brine's -res lasts 60s, meaning you will likely not be needing to re-apply it against the vast majority of AV's.

Solo, Corruptors can hit 5k -MaxHP debuff, but that's with a heavy slot and build emphasis for that purpose, which itself becomes quite niche. In teams, especially with other Brine users, it quickly becomes a fantastic effect that can stack concurrently. 

[tidge]

I went with:

 

Shoal Rush: Accuracy/Endurance Reduction w/ 4x%damage. I find it to be a reliable on-cast source of damage

 

Toroidal Bubble: I only have it holding one Resistance piece as a mule. I needed the slots elsewhere, and IIRC the resistance can't be enhanced... so 3x Gladiator's would (mostly) be a waste of slots in that case (unless boosting recharge maybe?)

 

Whitecap gets boosted Accuracy/Endurance (x2) and 4x %damage

 

Tide Pool just gets an Endurance Reduction

 

Brine: I went with 2x Accuracy/Healing

 

Shifting Tides got 2x Accuracy/Damage/Endurance and 3x %damage

 

Barrier Reef is holding 6x Reactive Defenses

 

Power of the Depths is holding 6x Preventive Medicine

FWIW an endgame AV has 30677.2 HP, and a GM 70679.18 HP. Whilst 5k isn't a negligible proportion of that, anyone trying to stack it to noteworthy levels really needs to remember @Auroxispoint about Brine's -HP getting less and less effective the lower the target's current HP is.

 

IME spamming it for the first ~10s or so of the fight makes a difference; but after that recasting it becomes kinda pointless.

I agree if solo, but in a situation with multiple casters applying Brine, the effects stack per caster and can easily be spammed with a Shifting Tides anchored on the target. I'd love to see an analysis of damage procs slotted in Brine coupled with it's debuffs in a team setting - absolutely deleting high HP enemies I reckon.

IIRC the only damage proc slottable within Brine itself is Touch of the Nictus... one damage proc combined with the flat -MaxHP is enough to one-click-delete low rank enemies but it won't even tickle AVs.

 

On teams -Res and -Regen Debuffs are always going to pull the bulk of the weight (Shifting Tide Inherent Cold Damage Proc shenanigans notwithstanding!) against tough single targets; and Marine has piddly -Regen. So personally I'd much rather just drop a Whitecap + Brine and then Blast rather than spam Brine repeatedly.

 

That said; with sufficient teammates and Lore pets to throw at something really all you need is Shifting Tides!

Ah that makes sense! My confirmation bias for thinking the Shifting Tides Cold "Proc" damage goes off because of the Brine application. I've only actually got ToN: Chance for Neg slotted.

It can be enhanced (if it couldn’t, you wouldn’t be able to slot resistance into it).

 

at ED cap for Corrs, it provides about 30% resistance to S/F and about 15% for everything else.  Nothing to sneeze at.

 

 But admittedly depending on what you’re chasing for set bonuses, Toroidal is a possible place to skimp on slots.
