These are some favorites traits, in order of most wanted to least wanted.
In general, armor with gold-level Stun Resistance (75% chance to resist being stunned) is very useful. If one of your characters is stunned they cannot move, nor attack.
Weapons with gold-level Interruptor trait (Overwatch attacks that are not Body Shots have a 100% chance of forcing the enemy to end their turn early) are also very useful.

Hunter[edit | edit source]
Luck Dodge Increased Weapon Damage (IWD) Damage Reduction (DR)
Hunter Rifle[edit | edit source]
Wide Bore Luck Interrupt Increased Crit Damage (ICD) Increased Crit Chance (ICC)
Hunters are much, much more useful once they have wide bore. Add high luck and you get lots of crits. Combine with ICD and the hunter charge move for really BIG hits. Interrupt works nicely here since you can stop entire lines of zombies and from long range. ICD doesn't make much sense due to the fact that hunters hit pretty hard already, and you'll usually be hitting multiple targets. More crits vs bigger crits will almost always be more advantageous.
Assault[edit | edit source]
Luck Dodge IWD DR
Assault Rifle[edit | edit source]
Increased Spread Luck ICC Interrupt ICD
Assaults are the early-challenge monsters, and late challenge cleanup crew. Increased spread will allow you to steamroll through the early challenges, and increased luck and crit chance to make them more capable of getting one hit kills. Interrupt is difficult to use on assaults, and my experience with it has been inconsistent. It seems like even with a 100% interrupt weapon, sometimes an assault won't interrupt everything in the cone of fire. ICD doesn't make sense due to the fact that you simply want more crits with an assault in general to bring their damage up to the kill range. Two assaults combined are really powerful, get two large overlapping cones!
Warrior[edit | edit source]
Luck Dodge Retaliate IWD DR
Sword[edit | edit source]
Arc Luck ICC Interrupt ICD
Warriors are the guardians of your squad. Getting surrounded? No problem! Stack dodge with luck, and if you have retaliate you get free hits. Large arc to hit as large of an area as possible, high luck and ICC for more big hits. Interrupt is also difficult to use on a warrior, as usually you'll just interrupt one thing anyway. You can take it, but generally I prefer it on my ranged attackers. ICD makes no sense due to the fact that warriors already hit decently hard - just go for MORE crits.
Shooter[edit | edit source]
Luck Dodge IWD DR
Pistol[edit | edit source]
Luck Interrupt ICD Range ICC
Shooters make one or two targets(with charge) dead, or stop one target from doing anything. High luck for more crits is always good since shooters do high damage, this allows you to definitely make tanks drop. However, ICD is also really awesome here due to charge ability synergy. Interrupt is GREAT on shooters due to their high damage. A half damage interrupt shot from a shooter is awesome for handling tanks and armored zombies if your melee is busy.
Scout[edit | edit source]
Luck Dodge IWD Retaliate DR
Scout weapon[edit | edit source]
Swift Strike Luck Interrupt ICC ICD
Go kill that one thing, scout. If you're lucky, kill two things or overwatch. Even though ICD synergizes with scout's brain stab, it's not very useful in general to take ICD. Scouts hit so hard already that you just want more crits and more swift strikes. Stack luck, icc, and interrupt. Like shooters, since scouts hit so hard, an interrupting scout is very strong.
Bruiser[edit | edit source]
Luck Dodge Retaliate IWD DR
Blunt Weapons[edit | edit source]
Concussion Luck Interrupt ICC ICD
Bruisers suck. Any time you stun something with a bruiser, you could have killed it with basically any of the other classes. More crits from luck and ICC is desirable since crits bring bruiser damage up into the range of being effective for killing. ICD synergizes with stun, but well, why would you bother finishing off a stunned target with a bruiser rather than another survivor?
Armor Dodge DR Health Wrestler
Dodge is the most important armor trait. Again, DR, and HP do not matter at all if you don't get hit. So, why DR over more HP? Because DR is HP agnostic and removes the damage directly from the attack. The bigger the attack, the bigger the raw reduction(20% of 100 = 20 vs 20% of 150 = 30). Additional HP does not scale in this fashion. Naturally, wrestler sucks - avoid getting into a struggle in the first place.
