EVE 101: On HP, EHP, and basic tanking

I'm not going to get into a philosophical discussion about tanking types (shield vs. armor and passive vs. active), but rather address this from a factual standpoint, so you can tank your ship however you please, hopefully better with the knowledge I provide you.

In EVE, HP and EHP are almost never identical. Total hit points (HP) are the combined raw shield, armor and structure points your ship has after any physical modules or rigs are added to provide additional points. HP is almost never equal to the damage you can take (or tank) though. There is basically one module and one rig (per defensive type) that increases your HP. Shield Extenders, Armor Plates and Reinforced Bulkheads are the modules, while Core Defense Field Extenders and Trimark Armor Pumps are the rigs. You will notice that there are no Hull rigs. That's because nobody really hull tanks. You just shouldn't. Installing these modules and/or rigs to your ship increases the base HP of your ship.

Effective Hit Points (EHP) is the combination of HP and resistances. I am going to talk about EHP as a static number, even though it's not. EHP varies from engagement to engagement, and , so please take the time to think about your EHP every time you engage, whether in PvP or PvE.

We are going to use a Gallente Thorax as an example. Below are the raw statistics of the Thorax:
Hit PointsResists (EM/Exp/Kin/Therm)

This ship (before any modules) has 5040 HP, but 6225 EHP vs. kinetic damage. That means if a single volley of damage were 5500 DPS (kinetic only) the ship would survive with a fraction of hit points (725 structure points).

How EHP works (in a perfect world).
Your ship can take a certain amount of damage (assuming no repair services) before it blows up. The more damage it can take (or mitigate) the longer it lasts before it explodes. Each ship has some basic resists to each of the four damage types, and some "holes" to some of the damage types.

In a simple world an 80% kinetic shield resist Thorax can withstand 6833 DPS of kinetic damage. In the real world of EVE, no weapon puts out a single damage type. Hybrids do Kinetic/Thermal damage, Lasers do EM/Therm, while missiles and projectiles do varied damage types. So most ships fit for at least two types of resistance.

Your EHP should be optimized to defend against the types of ships you will engage. For PvE this is actually pretty simple. PvE ships should fit against the (typically 2-3) damage types they will face. If you run missions (or rat) against Serpentis, that means you want to have strong resists against Kinetic and Thermal damage, since Serpentis rats usually utilize hybrid weapons. In PvP it gets more complex. A lot of PvP players fly Minmatar to provide them the opportunity to optimize damage against any opponent they encounter. Traditionally PvP ships try to balance resists across the board, recognizing that (for example) plugging the EM shield hole in Gallente is critical, because a good PvP pilot will utilize EM-focused damage against your shields, in anticipation of it being the weakest resist. However, if you know you are going to battle a fleet of Oracles, it's a safe bet to maximize your resists against EM and Thermal damage.

I don't want to get into tanking types, but just a brief comment so you understand that any repair modules affect your EHP. If you are active tanking, it's important to understand that your repairs are worth more than the raw numbers, due to EHP as well. For example, if you fit a Medium Ancillary Shield Booster on that Thorax, it repairs 146 shield hp every 3 seconds, but that 146 HP is actually worth 204 EHP (kinetic) in a basic Thorax in combat.

I hope this brief overview into how EHP works helps you fit your ships for better survivability.

Blog Banter 44: Capsuleer Identity Distributor (CID) Reciever

"The local chat channel provides EVE players with an instant source of intel of who is in the system. With a quick glance you can tell who is in system and what your standings are to them. War targets, hated enemies, friends and corp mates all stand out clearly. Is this right? Should we have access to this intel for free with no work or effort? Should the Local chat channel even exist? Should normal space be more like wormhole space where the Local channel appears empty until someone speaks?"

I've been silent a long time, that happens in RL. But this particular topic is one that has been on my mind since the release of Apocrypha, and then my introduction to life in nullsec shortly thereafter. I've played in all the areas affected by any change to local chat. I was a hisec carebear for a bit over a year before Apocrypha, and then spent a couple months learning the ins and outs of wormholes, but realized early on I didn't have the time to dedicate to life in a wormhole. Since then, I've spent time in both NPC and sovereign nullsec, as well as Faction War and lived in losec. Chat channels have been part and parcel in my game forever, and local most of all.

I've spent far too many cycles thinking about Local, and the intel it provides, and justifications for keeping it and losing it. I've refined and reviewed and regretted my position on Local over the years, but at this point I am comfortable with my position today. With that extended introduction, here's where I'm at with Local.

Local is a great intel tool. Knowing exactly who is in your system can be the difference between a ship and an explosion, but players have become far too dependent on knowing everything, all the time. Local in a wormhole is the exact opposite – you have no idea of anything when entering a wormhole, which in the beginning is part of the excitement and appeal. Somewhere between these two extremes is the appropriate solution. Here's my take on it...

First, the RP justification...

Due to the near godlike abilities of capsuleers, CONCORD implemented a unique identifier in the neurological upgrades that enable capsuleers to utilize implants. These ID codes broadcast on a specialized frequency that can be identified by the CID Receiver, which is deployed as part of the stargates, and utilizes the stargate network to broadcast the identity of all capsuleers within a system. Due to recent financial challenges, CONCORD recently announced that they would no longer cover the cost of maintaining the CID Receivers throughout known space.

Empires recognized the importance monitoring capsuleer traffic within their borders, so they took over the cost of maintenance for the CIDs internally. The factions that have sovereignty in NPC nullsec have taken over maintenance of the receivers as well, including NPC areas like Phoenix constellation in Fountain, or the Blood Raiders constellation in Delve.

The devil is in the details...

The CID Receiver ties into the Stargate network (which is why it doesn't exist or work in wormhole space). Whether offline or online, the CID Receiver will always broadcast the number of capsuleer signatures in a given system (local count). If online, the CID Receiver will broadcast the identity of any capsuleer who uses a stargate to enter or exit a system. There are no CID Receivers in Smuggler gates, so these gates will never broadcast the identity of a capsuleer who enters a system through a Smuggler gate. This means that pilots who enter systems via other methods (logon, cynosural travel) will not have their identity broadcast, but the local count will increment for each additional capsuleer who enters the system. Jump Bridges and Cynosural Beacons do not broadcast identities to the CID, so traveling via these methods do not display the identity of the traveler in local. In addition, upon entering a system, capsuleers can bribe the CID maintenance workers to block their identity when entering any system in empire space. Finally, in sovereign nullsec and Faction War systems, CID Receivers can be hacked to put them offline for 15-60 minutes (randomized based on the hacking success ratio). If a CID Receiver is hacked, all local identities are lost, and identities are only updated once the Receiver goes back online and pilots travel in and out via stargate. These two tools (bribe and hack) enable pilots to travel anonymously throughout any region of space.

In case it isn't clear, the CID is what provides count and identity of pilots in Local. Local in all known space systems will always have a count (Local [###]). Once a ship decloaks a pilot name will be added to the Local Channel list under the following conditions:
  1. The CID is online, and a pilot jumps into the system using a normal stargate.
  2. The CID is online, and a pilot undocks from a station in system.
  3. A pilot talks in local chat.
Hacking the CID
Hacking the CID is done with the Codebreaker module. When the CID is successfully hacked, the module goes offline and a timer appears on the module, counting down until it goes back online (automatically). Hacking the CID utilizes the Hacking skill, the meta-level of the Codebreaker module, and a formula to generate an offline time. This time ranges between 15 and 60 minutes, depending on the outcome. Note that any pilots who jump into the system while the CID is being hacked will be updated in local.

Bribing the CID
Bribing the CID can be done before a pilot decloaks. Bribe amounts are based on a combination of system sec status, pilot sec status, and (in FW systems) contested status. A bribe provides a 60 second delay before the pilot ID is updated in Local. Bribing also prevents the Faction Police (but not CONCORD) from tracking or attacking a pilot who has negative standing to the faction until the pilot ID updates in Local.
