Question about shield defense
The DOs that grant a defense buff are the purple ones directly below the damage enhancements.
What origin did you pick and are you a hero or villain? With that info, we can tell you exactly where to go to get your DOs.
Be well, people of CoH.

Your key powers are deflection and battle agility. Phalanx fighting is a small defense buff as well. Be sure to put several slots into each of those powers and you should be doing fine.
If you want more then look into the pools. Maneuvers, Weave, and Combat jumping are all common sources of additional defense.
In the DOs, if you right click on them it will tell you what they do. You want to look for a purple one with a shield int he middle.

General Slotting guidelines for Shields when using TO, DO, SO enhancements:
Deflection: 3 defense 3 damage resistance
Battle Agility: 3 defense 1 endurance reduction
True Grit: 3 heal 3 damage resistance
Active Defense: 2 recharge reduction
The defense that Phalanx Fighting provides to the player is NOT enhanceable. Do not waste slots in that power thinking that it will improve the defense it grants you.
EDIT: Wait, someone correct me here.
DEF(Melee, Ranged, AOE) +2.25% for 0.81s If target is another player
DEF(Melee, Ranged, AOE) +3.75% for 1.25s [Ignores Enhancements & Buffs] Effect does not stack from same caster
Max targets hit = 3
Does this mean that while solo PF still grants the user 3.75% defense (unehanceable)(if a scrapper) and then if two teammates are in range another 4.5(enhanceable)? Or does it mean that it does didly squat while solo?
Be well, people of CoH.

thanks guys

On a related note: most defense or resistance-based sets are pretty shabby while using TO's and DO's. When you hit 22 and slot SO's, your survivability skyrockets.

And of course there are SOs in the game lower than 25. I hunt them down in WW on a regular basis (and also, there's Mr. Yin's store you get access to from completing Penelope Yin's Faultline arc, but those are Origin specific). Pre-15 DOs, too.
Dec out.
I like using level 15+ Def/End IOs myself.

One thing I do on low level defence based characters is to place bids at the Auction House on medium sized luck inspirations. If you place your bid before you log off for the night to buy, for example, 10 at 250 inf each, you should have them all waiting for you the next time you log in. Using one of these inspirations will give your defenses a big boost for one minute, which will increase your survivablity in tough situations immensely.
Lamo if you haven't already, be sure to check out the Player Guides section of the forums.
Reading thru one of the Shield (tank) guides really helped me understand how to get the most +Defense out of that set.
Once you're all set up, there are only a couple of enemy groups in the CoH world that can even dent your defenses.
i was wondering how do i increase the def+ the skills this secondary class has i feel like i get hit for to much and i cant find any DOs that give + defense ? im level 18 btw electric shield
