# 1 DEM Mechanics
07-30-2013, 03:50 PM
Like many Engineering captains who are slowly finding their cruisers obsolete in modern-day PvP, I have decided to turn to Directed Energy Modulation to up my potential offensive capabilties.

Despite having commanded both Engineers and Cruisers since the games advent, I have never made extensive use of DEM. I'm aware that it boosts shield damage penetration, but other then that, I have limited experience with it.

So, my question for all of you, is this; how can I make DEM more effective? What powers, traits, and specs improve its performance? I'm aware that its impacted by weapon power, and that having DEM 2 and 3 is preferable. I'm also already in possession of the Marion Frances Dulmer DOFF. is there anything else that can be done to make DEM more potent? Other DOFFs, perhaps? Or certain skill specializations?

Also...regarding the basic effect of DEM; does using DEM simply convert a portion of your weapons existing damage into shield-penetrating damage, or does it add additional shield-penetrating damage onto the damage your weapon already inflicts? How does that work, exactly?

Thanks a ton in advanced, I appreciate it

Well beyond tactical captain buffs/ well timed usage combined with attack patterns I don't know how to increase its damage level other than to increase your own per hit damage, I can however tell you that DEM hits for damage based on your own damage generally DEM in my experience hits for about 10% of my weapon hit but also counts as an attack in its own right in the combat log so you get "your (insert weapon here) hit (insert target here) for XXXX (YYYY) shield damage", then you get "your (insert weapon here) hit (insert target here) for XXXX (YYYY) Hull damage" and after that you get "your DEM hit (insert target here) for XXXX (YYYY) Hull damage".

Put more simply, while DEM is based on your own damage output it adds extra damage to hull rather than increasing your bleedthrough, hope I helped

DEM is also a 'per pulse' effect. So for every 'pulse' of energy weapon fire you do. So the more pulses (like with single or dual cannons) of fire you put out, the more hits you will get with DEM. On that note though, it isn't as good with beams due to the smaller amount of pulses they do.

It's also affected by crit chance/severity, so Romulan BOFFs can help it hit a bit harder. Various hull debuffs can also help on top of that.

DEM can be quite effective however, and I recommend it's usage if you are wanting more bite out of a cruiser.

I've read this elsewhere and gave it a try. I can say, from my experience, the above is fact.

I've a chip on my shoulder about DEM, specifically DEM3. I could be wrong but this is my experience with it.



DEM is one of the worst abilities available imo. Especially DEM3 in the commander slot, it actually benefits engineers the least, despite being one of their top tier skills.

1st problem is that it's per pulse. Engineers are likely running beams on a ship that can slot DEM3, so it's not as effective. Cannons/turrets make best use of it, but those weapons rarely are used on a ship with a commander engy slot.

Apart from being more useful on non engy ships, the 2nd problem with it is the skill itself cannot be boosted that I know of (weapons training and energy weapons skilling doesn't count, they should be 99 each on all toons anyway). Ignoring buff/debuffs the extra damage it does is FIXED. More powerful weapons, more sub system power, consoles or higher end skills doesn't affect it. It just adds a fixed predefined X extra damage directly to hull per pulse. Its not shield bleed through (which it really ought to be).

If it were based on a percentage of weapons damage it'd be great (beams have higher DPV and would actually benefit the most). But no, it's fixed. This means that as ship hulls have beefed up over time and now with fleet ships, DEM, which hasn't changed since inception, imo is really lagging behind as an ability. Its behind the times.

The 3rd problem is that the extra direct hull damage is so small the direct to hull damage can be shrugged off by even the squishiest of escorts and their passive hull regen.
Best case for a typical engy cruiser, 8 beams. 8*46.7=373 damage per 8 beam volley with no tactical buffs/debuffs (something a ship with DEM3 is unlikely to have anyway). Pretty sure that's worse than a single turret shooting directly on unshielded hull.
I can do more damage per tick of eject warp plasma 3 burn on a shielded target (450+).

4th problem, long cool down time. Ok it lasts for 30 seconds, but then it's down for a full minute (or 1m30s? cant remember) after that. It's spends 2/3 of it's time offline. Only doing aux2batt or photonic officer builds can reduce that.


The only, ONLY reason to use DEM (and a good one at that), is to slot DEM1 and equip a System Engineer doff to grant weapons drain resist on use of DEM to keep up higher DPS when using beam overload or fire at will. So one has to use a doff slot to make the skill worthy.

Commander level engy slots are better used on other skills imo. Even Aceton beam 3 does more damage to hull (~80) per tick than a pulse from DEM3 (~45) and that's just it's secondary effect (and radiation can't be resisted either?).


Perhaps someone can point out where I'm wrong, but DEM, especially in the LTC and COM slots is I feel pretty darn underwhelming/usless and out of touch with current ship stats.

Dem should be used in conjunction with aux2batt, 3 purp technical doffs, and purple Marion. Those will reduce recharge times and energy usage. Most cruiser guys use it with beams, but any ship can use it. Dual heavy cannons get the most out of it due to high initial damage.

Problem is it takes a lot of healing abilities out, hurting escort survivability.

Strange that you get such a small amount of damage per DEM hit as I get about 10% of what my beams do (which is about 1000 dmg per hit) so when I use 6/7 beam arrays I easily get 8 or 9k per broadside volley and get 800 to 900 from DEM as part of that volley, times that by 4 to get the cycle damage and it becomes something fairly worth having.

personally i believe that if you don't have a marion doff, don't go for DEM of any tier.
for PVP extend shields is a better choice imho, that should add majorly to the survivability of your grp.
for PVE, especially stfs, EWP would be my choice. Or EPtW/S 3, the +% resi or dmg comined with 100% uptime is also a good option, imo.

For a Beam boat cruiser the only options for the top commander ability are Warp Plasma 3, Aceton Beam 3 from the trainer on ESD.
Maybe I am forgetting something, but DEM3 supplements the beam damage best and is a good choice you can train with an engineering captain.

Not sure what other powers are available from BO training.
