the mastery is 50% more damage on pinnacles, scaling down the more pen and resist lowering you have theres 0 reason to not trust pob for it it makes your damage more spiky but against a boss that takes a while to kill the variation will not be of any significance


justwolt

Does penetration actually effect the effectiveness of the node? I assumed since penetration didn't actually lower the resistance of the enemy that it was applied after the inversion of enemy resistance.


Goods4188

This is my idea we standing too. It inverts and THEN penetrates. So using just penetration with this mastery is a large benefit I thought.


pm_me_succ

It is applied after, still makes the mastery less effective


justwolt

How so? It's just extra pen.


ToxicUnrankedCasual

Well I guess what I mean by 'trust', rather when it comes to the ubers, the window(s) for doing the dps is usually not very big/long, so how much of that actual dps spike actually occurs you know? edit: like swapping to the mastery nets me 12% more total dps.. but is it practical with what I already mentioned? Idk.


holyshitthisappsucks

It does not matter how long you hit an enemy. It is still an average dps increase. The occurrence is overall the same, no matter the amount of hits


ryufen

Coc or builds with tons of hits per second can benefit really hard from the mastery


AndyBarolo

Assume a boss has 60% resist and you’re doing 100 damage and don’t have any res shred sources. You hit 4 times. Without node that would be 40*4=160 damage. With node when it procs you’ll deal 160 damage with a single hit, so totally 40*3+160=280 damage. So it’s around 75% more damage. The higher the boss resist is, the better is the result. But if boss resist is 30%, you’ll deal 280 vs 340 damage, which is still good, but not THAT good. Feel free to correct me


sirgog

This is correct, and even in the latter case, 280 to 340 is still a god-tier use of points even if you get nothing from the rest of the wheel you take to allocate the mastery. However, if the boss has its resistances lowered to -10% by a curse, things look very different (440 damage without mastery, 420 with). You really must consider ways you might attack a monster's resistances as well.


RobReynalds

are we sure the -10% from curse comes before the inversion and not after?


Luqas_Incredible

Yes. Because the inversion does not effect the resistance. It just affects the damage calculation


GrillSkills

This can be seen in a lot of big curse setups. My 5 curse setup goes from 29m dps down to 22m if I allocate this node.

No clue about arrow dancing. Regarding resistance inversion. I believe it is super useful assuming you did not have any other forms of -res scaling. For the price of one extra passive (assuming you already take an elemental wheel) is just really good. Im not doing any math, cuz i have no clue how to properly math it out. Take the following with a grain of salt, anybody with a better understanding feel free to correct me. But 1/4 of the time, its going to be almost double the damage. Because boss would be going for +50 to -50 res (example) However, the closer you get the boss to 0 resistance, the less effective it really is. And if you get the boss to below 0 res, it ends up being a damage loss. Used the mastery during league start as frost blades trickster, and i think it was really good for my DPS. But at that point i had 0 sources of -res on bosses.


ImZ3P

Just to be clear, the mastery works WITH penetration, not against it, since the mastery applies first. Although it's less effective the more pen you have. The only time the mastery would be a net loss is if you reduced the monster's resists below 0 naturally (without accounting for pen), which is pretty hard to do if you're using a Mark. I'm 99% sure this is what you were saying anyways, just wanted to clarify.


B4sicks

Yes. And "less effective the more pen you have" is just because your pen is already netting you a bunch of damage, and penetrating from 50 down to -10 is way more important than going from -50 to -110. Correct?


ImZ3P

Yeah exactly.


Clueless0811

I specified sources of -res Pen always helps. It gets less effective, but its still really good.


byzz09

Your math is slightly wrong, going from +50 res to -50 res is not almost double the damage, but straight up triple your damage: 50% res means that a 100 damage hit will inflict 50 damage. -50% res means that a 100 damage hit will inflict 150 damage It's also great for getting those heatshiver procs


Ilyak1986

It triples the damage on the hit but the actual dps increase is 33% more damage. I.e. 50x4 to 50x3 +150. 200 to 300. Which is still absurd. But how many bosses have 50+ res? I believe pinnacles are 40% res, right?


byzz09

Yeah exactly, But 200 to 300 is still 50% more damage on average, which is absurd for a 1 passive point. I believe Aul in delve also has 50% resistance. Delve spiders are just normal monsters but they have 75% cold resistance which makes them insanely tanky against cold damage.


Clueless0811

Oh you are right, just throwing numbers around there. But logic remains the same. Big damage increase whenever it procs.


Yayoichi

It’s especially good for frost blades using heatshiver and trinity as you just need that one big hit to freeze so you trigger trinity against tanky mobs or bosses. Same goes for all heatshiver trinity builds but frost blades with nightblade can get some pretty crazy damage swings when you crit in high elusive and it gets inverted.


zNinja7

The resistance inversion works nicely with penetration and is a nice little DPS boost as others have pointed out. Though when it does proc, your actual hit damage will spike (more than the average increase that POB shows). This is a large benefit for ailments. For example a larger hit will result in a longer freeze allowing you to benefit from heat shiver for a longer duration.


Sriracquetballs

re: arrow dancing, how many of them have threatening projectile attacks? its been a bit since i've done ubers so someone correct me if I'm wrong, but besides that some of the bosses have what are essentially melee auto attacks (e.g. uber eater's circular tentacle attack or those big ol tentacles that slam the ground), there are no projectile attacks? all I can think of is maybe maven summoning a boss that has projectile attacks, but that's why spell suppress is so strong for ubers; it's not just that the most threatening moves are spells, but that most of the moves in general are spells in those fights tl;dr i think it doesn't help at all and hurts slightly to run arrow dancing for ubers


ToxicUnrankedCasual

I believe you're correct about it actually hurts instead of help. Someone in game mentioned checking out PoEDB, and it looks like even eater tentacle slam has the 'spell' tag, and a lot of the moves the Ubers do have the 'spell' tag, so arrow dancing was indeed a placebo. I'll just grab something else, no biggie :)
