- Poise is an in-game statistic that increases your resistance to being staggered or stun-locked as an effect of taking hits from opponents. (Further clarification needed)
- Interrupt: an enemy's attack interrups your action
- Staggered: an enemy's attacks causes you to temporarily be paralyzed, leaving you vulnerable to consecutive hits.
- Stun-locked: being staggered continously.
- Endurance and Adaptability contribute to your natural poise if raised equally. In other words: if you have 20/40 END and ADP, the contribution to your poise will be limited by the lower, to 20. If you have 40/40 END and ADP, then the contribution to you poise from these stats will be 40. Raising the lower of the two always results in poise gain.
Poise damage is only reduced on a glancing blow. A glancing blow is when you for example hit with the very tip of the weapon and it does reduced damage. I haven't done that much testing on them, but it seems that the percent of poise damage reduction on glancing blows is maybe proportional to the percent of regular damage reduction. Note that some weapons, such as spears, will do the most damage at the closest distance and won't do as much where you would think that they would.
Stone ring adds 30 poise damage to every attack. Every time damage is dealt, 30 is added to the poise damage that damage instance normally deals.
When an attack hits you and your poise is depleted, as soon as your stagger animation ends your poise is instantly reset to full. Since the stagger animation must end, if you don't roll away from R1's you won't reset your poise and will continue to be staggered. When an attack hits you and your poise is not depleted, it begins to refill at a rate of 0.56 poise per second, regardless of maximum poise or current poise. That's all. Poise regenerates at 0.56 poise per second. This is so slow that poise can be effectively considered nonregenerative.
Let's do an example on why poise is effectively nonregenerative. You are fighting with 55 poise and your opponent hits you with a 1H R1 of the Rapier. Your poise is now lowered to 20 and you are not staggered. Let's see how long it would take for your poise to come back enough to not get staggered by the next attack. We need 15 poise to regenerate to be above 35 poise. 15 poise divided by 0.56 poise per second gives us the amount of seconds it will take. The calculation comes out to 26.8 seconds. Poise regenerates so slowly that the only good way to get your poise back is to get hit down to 0 poise to allow it to instantly reset.
There are many attacks that have a poise damage value and subtract from your current poise, but will normally always stagger you. The only time they will not stagger you is when you are within hyper armor frames, which I will go over later. The attacks with this property are all highlighted in red on the spreadsheet. Let's have another example of how this can affect you. Once again, you have 55 poise and you opponent is 1 handing the Rapier. He hits you with a rolling attack, lowering your poise by 28 and staggering you, because rolling attacks always stagger. You are now left with 27 poise. He now hits you with a 1H R1 and it now also staggers you because the rolling attack both staggered you AND lowered your poise. If you're wondering how long it would take to regenerate the 8 poise needed to be above 35, it would take 14.3 seconds.
Next, let's go over what hyper armor frames are and which weapons have them. For a certain amount of frames (I don't know how many) before and a bit after an attack with most great weapons, there are hyper armor frames. When you are hit with an attack while you are within hyper armor frames, all poise damage is halved and attacks that normally always stagger are now poisable. The attacks with hyper armor frames are all Ultra Greatsword attacks, all Great Axe attacks, all Great Hammer attacks excluding 1H Rolling and 2H R2, Halberd 1H R1, 1H R2, 1H Rolling, 2H R1 excluding Helix Halberd 1H R2, and parries with these weapons. No other attacks have hyper armor frames, although I still need to look at powerstance so some of those attacks might have them.
Example time! Once again you have 55 poise and your opponent is using the Rapier one handed. You are wielding the Zweihander. Your opponent hits you with a 1H Rolling attack but you are not staggered because you timed your 2H R1 properly to utilize your hyper armor frames. The 28 poise damage of the rolling attack is halved to 14 and you are left with 41 poise. Your opponent then hits you with a 1H R1 when you are not in hyper armor frames, but once again you are not staggered because of the reduced poise damage on the rolling attack. You are now left with 6 poise. As this example shows, hyper armor frames are extremely strong and proper utilization of them is very important for great weapon play. Also, before the Iron King patch (or was it Ivory? Don't remember which patch removed it) the Great Hammer 2H R2 did have hyper armor frames. Properly understanding how hyper armor frames work shows the magnitude of that nerf.
Hopefully I explained everything and didn't forget anything. This next part will go over the methods used to find all of this and how to reproduce my results. Let's first go over how I found the breakpoints. Of course, Cheat Engine was used to monitor and edit my current and maximum poise. I set my current and max poise to 1000 (it can be any number) and then got hit by an attack and recorded the drop in current poise. Because I was put into at least a half stagger my poise did not begin regenerating immediately, so I could record exact poise damage. For finding which attacks need hyper armor frames, I either just walked right after being hit or I casted and held down the cast button for Sacred Oath to lock myself in an animation.
Next let's go over how I found the speed at which poise regenerates. I set my max poise to 100 and then set my current poise to 0.001 and timed how long it took to regenerate, then repeated. The results were both 178.xx seconds. Then I set my max poise to 10,000 and set my current poise to 0.001 and lapped the timer at every 100 poise regenerated until I was at 600 current poise. The results were all 178.xx seconds. I averaged the 8 tests and then divided 100 by the average to get 0.55978 poise per second. After rounding, poise regenerates at 0.56 poise per second. Finally, I will explain how we found which attacks have hyper armor frames. My partner would draw a greatbow arrow and fire it at me just before my attack hit him. We would repeat this until I did not get staggered by a greatarrow, and if we couldn't do it after a long time we determined that that attack did not have hyper armor frames.
