Fulmens

The damage got cranked up on Dragon's Tail a while back. Although, now that I look at it, the damage also got cranked up on (claws) Spin and Whirling Sword/Lotus Drops always had that DOT effect. As Sailboat said, it's a pretty good AOE. (1.5 second activation, all the damage lands NOW.)

I played /Traps to 50. Slow and deliberate. (Dark/Traps, for extra leisure.) I played some /Devices. Deleted at 29. I have to disagree that "it's a good set for that."

[ My initial answer was "You could play /Energy and take a bite of sandwich before every spawn and still be faster than /Devices." Which is true, but you do need to be a twitchy player for that style. ]

You don't get malnutrition from SO's.

... maybe this is a better metaphor than I'm giving it credit for.

I made most of my inf on a L20 rad/sonic defender in the Steel Canyon Wentworth's.

This. The defense equations in this game are somewhat intricate, but probably 90% of the enemies you'll fight have a chance to hit that's (50% - Defense) * X where X varies with level, rank, etc. and the (50% -Defense) has a 5% minimum floor.

"Everything" isn't a useful answer, so I'll go through some of the strategies as I understand them. Now I've made several billion crafting recipes, a billion or two on currency exchange and almost nothing doing anything else. So I'm out of my field of expertise.

FLIPPING RARE SALVAGE: My understanding is that you buy orange salvage "near the bottom" and sell "near the top", in stacks of 10. I tried it a couple times and, at the time, couldn't make it work. So let's say, making up all numbers, that Hamidon Goo has "last 5" sales prices of 1,300,511/1,300,511/2,000,000/1,300,511/1,900,908

Someone's got a stack of bids in at 1,300,511- or several stacks of bids, totalling a couple hundred probably- and is selling for...you don't know what. It's probably under 1,900,908 and over 1,500,000 ... if it's too low people won't round up to 2 million. If people buy for 2 million consistently- most people use round numbers-they are getting 1.8 million per sale (Wents takes 10% of the total) and making just under half a million per sale, or 5 million per stack.

You can fight with them, running up the buy price and running down the sell price. You can try sneaking your bids in (bid exactly what they do and split the purchase) but you'll still have trouble figuring out the "right" sell price.

FLIPPING RECIPES: You pick something that there's a lot of movement in (Doctored Wounds, level 50, for instance) and do much the same thing. Unlike salvage, you can probably buy for 1.5 million and sell for 3 or 4 million if you pick the right recipes. I have only done this a couple times. I'm told that with the right choice of recipe the profits can be ENORMOUS.

CREATE ARTIFICIAL SHORTAGES: This one is a lot harder than it seems. The idea is that you buy up the entire existing supply, put in bids to catch the new supply as it comes in, and sell your stuff at an extortionate price. I tried this once, in the middle of another experiment. I had almost a billion invested in Respec Recipes villainside and nobody was buying mine. At all. I ended up taking a slight loss and shoveling them out the door a little below what I paid. If it's an expensive item, people will wait for you to run out of money. If it's an inexpensive item, you won't make enough to blow your nose with. (People DO run the market in various items from time to time, short or long-term. It's stupid, it's a lot of work and it doesn't make you squat. But people do it. )

CURRENCY EXCHANGE: You need to be a known and trusted person to do this, and a multibillionaire. Offer to take influence and give people infamy, or the other way around, and charge them for the privilege. I do this- I charge 10% on some servers and 20% on the ones where I don't keep my money. If I don't have to move my money from one server to another- I just take their money redside and give them less money blueside- it's a 10% profit. If I have to move money from server to server that takes up 10% of it. Worst case, I move the money twice and break even (within a percent). Best case, I move the money zero times and make 20%. I think on average I make 5% or so; 50 million on a billion inf transaction.

CRAFTING AND RESELLING: (aka "Crapping" for crafting and flipping) This is what I do. It's very easy to find something that will make you 5 or 10 million inf per transaction, although there are a lot of niches that someone "lives" in. 30 or 40 million inf per transaction is possible. In those cases it's very possible that you'll get into a price war. I'd start by finding a level 50 recipe that
1) moves frequently (you want "last 5 sales" over a couple days at most)
2) has around a 10 million inf spread between price of recipe and crafted
3) Does not have a LOT more selling than bidding for the crafted IO.

Put in bids for 3 recipes, and 3 of each salvage needed. Wait a day or so. Collect everything (if any common or uncommon salvage didn't fill at your price, pay BUY IT NAO prices). Craft your 3 items. Put them up a little below "market" prices- let me take a minute and explain this.

[ START EXPLANATION]
If the last 5 sales are all 20,000,000 and you put your doohickey up at 20,000,000 it will not sell. Sales will go on and on, and yours will not sell. Why? Because buyers throw round numbers out there. If you put up ten items for 18,000,001 then probably nine of them will sell for 20 million. Regular sellers know this and sell for 19.5 million, or 19.1 million, or 18.6 million- the game is to be higher than the buyer's "Cheap" guesses and lower than the competition.

There's not a LOT of competition, by any sane standard. I threw up a Regenerative Tissue: + Regeneration once for something like 32 million. The next day it had sold for 45 million. Nobody tried a number between 32 million and 45 million... people are throwing money around like it's imaginary.
[STOP EXPLANATION]

And then wait a couple of days for someone in a hurry to buy your stuff. It's very good, very easy money and I've done it on fifty or a hundred different items.

Trick-or-treating.

As someone told me once, "the squeaky wheel gets the hammer." Prove that Traps, with its defective tier 9, is underperforming compared to other complete if you want it fixed. Repeating "Trip Mine sucks" will not actually help.

(Personally, I'd push on the Devices end of things and hope the fix translated to Traps. Because I do believe that Dev is underperforming by Blaster secondary standards, and that's a pretty low bar.)
