It does indeed give you some protection against ALL attacks. Here are the stats of the Anti-stab Vest: ballistic = 0.1; bleed = 0.98; Don't be fooled by the "ballistic" stat, that also protects you against melee attacks as well. More than anything the Anti-stab Vest will reduce the chance that you will bleed (see the "bleed" stat above) after being hit with a melee weapon in the chest. This does not reduce the chance that you will bleed if you are shot. Again, melee only. Given that very few items in the game have "ballistic" protection, I would say the Anti-stab Vest is indeed worth it. This is mostly correct. The Plate Carrier and the Press Vest share the same stats: ballistic = 2; bleed = 0.9; This is also true for the Assault Vest and High Capacity Vest (in that they offer NO additional "ballistic" or "bleed" protection). Yeah, I also imagine the rework to the damage system will completely change this. Also mostly correct. Your friend was protected by both the Plate Carrier AND the items inside his Plate Carrier. If you are hit in the arms or hands, then only your shirt/jacket will absorb the damage. You need to get hit in the chest or back for the vest to come into play. There is truth to Wobo's testing. When you are hit with a melee weapon or projectile, DayZ checks to see what part of your body you were hit in and what clothing/gear is worn there. It then damages the clothing/gear, reducing the incoming damage based on item condition and armor stats. It then checks to see what was in that clothing/gear's inventory and damages each item, again reducing the incoming damage slightly (based on the hit item's condition). It does this for every article of clothing or piece of gear in the slot you were hit. So, theoretically, having 10 1-slot items in your Plate Carrier as opposed to 1 Protector Case and 4 1-slot items would offer you more protection as DayZ treats the 6-slot Protector Case as 1 item (for a total of 5 items). I imagine this is where the PvPers folk wisdom is coming from. Correct. This is both true and it's not quite that simple. There are a lot of other factors that come into play when DayZ does damage calculation, but yes, having items stored in your inventory does reduce incoming damage. DayZ has some of the most fascinating and complex damage calculations I've seen come out of a game. I think if folks knew all that was involved in DayZ's damage calculation, they'd have much more respect for and appreciation of DayZ and BI. Let me know if you have any questions!
