Blood Brother + Coven's Criterion

Do Blood Brother work well with Coven’s Criterion? How much they reduce damage from blocked attacks together?

It’s not forbidden to experiment and make one’s own fun builds - but if you want guidance on some of the best and most efficient builds you can look at maxroll and icy veins… and also youtube. You can use google and search: maxroll crusader build… just as an example.
The builds presented can usually be tweaked to your personal liking if you want more toughness for example.

I want to test something for fun. I know best builds are on maxroll. I always look up things there. But I want something for fun. That is why I ask. I wonder how they work together. One reduces damage from blocked attacks by up to 60% and other by 30%. So together it is 90% (addative) or 72% (multiplicative). But is it even worth adding Coven’s Criterion if we have extremely good damage reduction (mitigation) and big block amount (Hallowed Bulwark)? If we had that probably blocks would reduce damage to 0 so no damage reduction from blocked attacks. So would it be worth using Coven’s Criterion? Or is it only good if we have lower mitigation and/or lower block amount?

Generally speaking damage reduction can work like this (if I’m not totally off): if you have a series of items or skills or whatever that each reduces damage by 50% then it goes like this; the first item takes 50%, the next 50% is worth 25% so the combined reduction is now 75%, the next gives 12,5%, so you’re on 87,5%, the next is worth 6,25, so we have 93,75% and so on. But even with high mitigation we can be killed when we go into higher and higher greater rifts because the damage taken is so high that even a few percents are deadly and when we put too much into damage mitigation we lose the ability to do enough damage to kill the monsters.
The only time we can be invulnerable is in ordinary rifts with Goldwrap and Boon of the Hoarder where armor can go up to 99,99xx if we get enough gold so we can stand in multiple molten explosions without dying.

Very few things are additive in D3. Damage reduction is not one of them. If you are trying to make a block build you can try adding justice lantern there. It always rolls with block chance as a primary stat and it will also translate a percentage of your block chance into pure damage reduction. Assuming that you 're playing a crusader, well, coven’s is not really good, possibly because most builds use a shield that has a multiplier related to a skill that you are using. As for the blood brother, it is not bad. I used it last season with the 4th slot as something extra, but i wouldn’t replace my main weapon with it otherwise. If you are going full block and toughness you will be inevitably sacrificing damage. Could work for a support build, but there isn’t a good support crusader right now - i don’t know if support crus is even a thing in the game.

Not since Season 4… https://d3resource.com/seasons/index.php …and I seem to recall it had something to do with them changing Consecration / Bathed in Light so that if you had multiples of these overlapping, the healing provided no longer stacked, i.e. they stopped the Crusader being an effective healer.

The first thing that needs to be clarified is that there are two Block values of importance.

  1. Block chance, i.e. how likely are you able to block the incoming attack.
  2. Block amount, i.e. when you successfully block, how much of the incoming attack’s damage is mitigated

I’ll use my Invoker as an example…

As you can see, her base Block Chance is 31%. In combat, that will rise (due to abilities) and whilst the in-game tooltip says this chance caps out at 75%, that’s not actually true. You can actually get Block Chance to be over 100% with the right combination of skills / runes / gear / cubing. However, that’s just deciding whether she successfully blocks or not…

Assuming she blocks, that’s when the Block Amount comes into play. That’s how much of an incoming attack’s damage is mitigated / ignored. So, say a mob was going to hit me for 500K damage. With a Block Amount of 25.0-32.8K, the incoming damage would be reduced to 467.2-475K when the Block was successful.

Even if you get Block Chance to 100%, you’ll never get Block Amount high enough to mitigate a lot of damage. That’s why you need stuff like Armour (from gear and STR) and All Resist (from gear and INT) and defensive items such as Justice Lantern, Aquila Cuirass, and so on, and why shields / weapons tend to be picked for their offensive legendary abilities, not their blocking chance.
