While on the subject of the auto-blocker, it's got me looking at my own itemisation set-up for Felmyst. As covered a page or two back, the incoming damage is pretty trivial of course, but I don't mind chugging more mana pots if it means our healers save some more mana.

I, like I would imagine most would, use Figurine of The Collosus for the use and the extra blocks in general. Previously I've used Dabiri's aswell.

In the general case for predictable low dmg from multiple sources I guess there must be some kind of relationship between frequency of incoming hits, size of the hits and the amount of block value/% you already have that can be derived to compare the Auto-Blocker and Dabiri's.

I'm not fantastic at theorycraft, but I'll give it a go and you lot can correct my shocking logic/maths.

Dabiri's

You could use the frequency of incoming hits to derive Redoubt/Holy Shield up-time to work out the number of incoming hits a second required to ensure that the full use of Dabiri's is well, used (15.85%), or how much of it would be used (this is assuming that without redoubt/holy shield you have more than 17.88% [15.85 + 2.03 passive] "to be hit" on your combat table, I fair assumption I think).

Once this is derived you could work out how many hits per time (the time being arbitrary as both trinkets have the same up-time a minute of 10seconds) blocked due to the additional block rating and add to this the 2.03 of total miss/parry/dodge/block gained from the passive defense on the trinket.

This can then be multiplied by your current block value to find how much damage per time is reduced from the trinket.

Auto-Blocker

As for the Auto-Blocker, we're looking to find out how many times you currently block per time, and how much of the passive/use block value is.. used.

To work out number of blocks you would add the passive block from gear (minus level difference of mobs 0.2% per level above) to the Redoubt/Holy Shield up-time worked out previously.

Then you would need to minus the current block value from the size of the incoming hits (after armour etc etc etc is applied) to see how much damage is available to be blocked. If this is more than 370 (259 x 1.1 Metagem x 1.3 Shield Specialisation), then the full usage is available with the use and you get an average additional 131 dmg per block mitigated. If less than 370, the amount less minused from the on use amount of block value multiplied by 20/120 will bring about the average additional dmg per block mitigated (up to the point of the on use effect is actually not being used, I don't think that 59 block value could ever be better than 2% avoidance in an aoe circumstance for pure total damage reduction.)

Therefore multiply the number of blocks found previously to this additional damage reduction per block to find the damage per time reduced from the trinket.


I can do the maths on my own gear in my own time, firstly:

1. Correct my maths/logic.
2. How do you work out Redoubt/Holy Shield uptime from frequency of incoming hits?
3. How do you work out Block Value given Tome of The Lightbringer?

Cheers.
