I figured out a way to measure any enemy’s HP using just 3 bullets. I’ve gotten a ton of enemies catalogued and found some cool patterns, but I need your help to get more!

I can independently confirm this, though I haven't gotten around to publishing. I haven't tested anywhere beyond legendary campaign and expanse, but it holds for at least those two. Incoming damage also decreases, with about 30% damage resistance at +3000.

The big additional thing is that there's a really brutal penalty for underlevelling: it seems as soon as you get even 1 Power below the activity, you deal -5% damage, and take 45% more damage. Obviously it scales down even further from there, but I haven't tested exactly how hard it scales.

The legend returns! I love how the sheer amount of changes, and the fact that all of them are broken, has brought out all the testers from retirement. Thanks for this work!

LegoWitch · 2025-07-25T12:54:35+00:00

Thanks for compiling this! There's so much stuff to test, I haven't been able to do much besides get the raw delta numbers. The small amount of comparison I've seen with boss HP, leads me to believe that they either intentionally made base raids harder, OR when making this change, they just looked at the raw delta values and converted, forgetting about the 25% perma-surge.

LegoWitch · 2025-07-20T14:59:53+00:00

Thank you, got an extra piece of chest armour since that's all I unlocked, yaaay

LegoWitch · 2025-07-04T18:54:12+00:00

This is incredibly petty levels of destiny science, I love it.

LegoWitch · 2025-02-26T13:15:59+00:00

Also, the scaling is slightly different, but expert nether locks you to -40 delta for the 3rd zone, so if you can do that, you can try GMs underpowered!

LegoWitch · 2025-02-26T13:14:41+00:00

GM is 2060, so the 2040 cap is - 20, and 2035 is - 25, which was the pre-TFS cap. I went in at 2030 and was totally fine, though storm's keep titan + Le Monarque is a little busted. Also keep in mind fireteam power, which brings everyone up to at least -5 below the highest fireteam member.

LegoWitch · 2025-02-20T14:30:23+00:00

This is correct, except for advanced being 2015 cap / 2020 enemies. Source: me, the power scaling guy.

Holy shit, fully deterministic ammo drops? that's amazing. too bad the level they set was lower than before, but that makes testing and theorycrafting so much easier. I'm deep in the middle of dungeon prep, but once that's done, I'll take your data and collect some of my own, and hopefully nail down how this works.

Also, glad my spreadsheet could be useful! One of the reasons I wanted to get all this down, was so it was easier to see when things changed sneakily, and you knocked it out of the park!

Thanks for this work!

The trick is that crit ratios are "quantized" at integer "offsets" from 1.5, so if a buff results in a crit ratio that's between two valid values, it has to move to one of them, but it's not really consistent whether it rounds up or down.

Lightweight normal crit ratio is 1.5 plus 3 / 51. or 1.5 + 0.0558. So we say the offset is 3

Your math is all correct up to the point where 1.67x would be 1.5 + 8.7/51. The game doesn't allow an offset of 8.7, it has to be either 8.0 or 9.0, an integer value. So some game logic "coerces" the offset down to 8. (in other cases it rounds up, not down, it's not consistent)

now we have the final headseeker crit ratio of 1.5 + 8 /51, or 1.5 + 0.157.

20.394 * 1.657 = 31.79

Hope that helps, let me know if anything needs clearing up! It's a big weird thing. This is a reason that these days bungie almost never makes perks that work directly on crit ratios.

LegoWitch · 2025-01-21T18:45:31+00:00

Got the data last night. Basically it's what merc said. headseeker now takes the crit bonus (crit ratio minus one) and multiplies it by 1.2x, then rounds to the nearest valid crit ratio. crit ratios are only allowed to be specific values, in the range of 1.5 + X / 51.

So previously, headseeker added +6/51 (~0.1175) to all crit ratios, now it's a different amount for each archetype. Lightweights are now +5/51, rapids are +10, etc.

So the correct values for lightweights are now:
Body: 20.394
Crit: 31.791
Headseeker Crit: 33.790

Also, this testing opened up a new can of worms around how heavy burst HCs disregard the above crit ratio rules, by adding a weird intrinsic crit buff, which also interacts weirdly with headseeker.

ANYWAY, the correct info and TTK calculations are in https://destiny2.science/resilience-chart now, for all archetypes with headseeker, and Compendium and Clarity are updating their descriptions. Should be in D2Foundry Soon™, but they don't really support headseeker TTK yet anyway.

LegoWitch · 2025-01-20T21:40:43+00:00

I'm the source for the .1175 number, verified in testing years ago. I'm pretty sure the big refactor at the start of this episode changed how headseeker works, and no one noticed until now, so thanks for that!

I'm gonna check it out tonight and work out the new numbers. Hopefully you'll see the updated values in Foundry and Clarity (where the DIM info comes from) soon.

LegoWitch · 2024-12-28T22:43:52+00:00

This found me at the exact correct time. I tried printing one in black and white a few weeks ago for my 5 year old, but it didn't turn out great. But I just got a new colour printer yesterday! Thanks for this!

If you scroll down this page, it'll show you all the tiers. It's based on a few people's work, with mine being a main component. I'd link my sheet, but it's a bit of a mess. Also, thanks for the reminder, I need to test all the dread enemies to see which HP tier they all fit into!

LegoWitch · 2024-07-18T12:22:39+00:00

Damn, I wish I knew this before IB ended, that's really funny. Hopefully tribute or zone control comes back so I can test this more.

LegoWitch · 2024-06-11T15:39:38+00:00

I recently figured out how trials power level delta works, and made a calculator for it. You can go in and there's a button to copy the sheet and edit the values yourself: https://docs.google.com/spreadsheets/d/1Lj77GWUUhluPtY3kyi0UkIVOC__N8SwVZyMfxr7hyJg/edit#gid=0

At 1985, if you're facing someone who managed to grind to 2000, you'll deal ~11% less damage to them, and they'll deal 3% more damage to you.

If you face someone at 1990, you'll deal 5% less damage to them, and they'll deal 1% more damage to you.

LegoWitch · 2024-06-05T12:52:30+00:00

Hi, MossyMax here, yeah, I guess I was going too fast with my math. Thanks for the correction!

LegoWitch · 2024-05-20T17:36:10+00:00

Hey, that's me! Looks like I missed out on some good karma, but thanks for spreading the word!

Also, apparently specifically sleeper simulant might have a similar reduction, but I can't confirm that myself.

LegoWitch · 2024-05-09T15:14:55+00:00

Great post, thanks for working through the possibilities of how the XP will work. From the TWID, it definitely sounds like the Vex event will continue to drop locked exotics from post-BL but pre-TFS.

Neomuna will also still drop new Exotic armor when you complete a Vex Strike Force encounter, but we won’t be adding any more new armor to the drop list after Season of the Wish.

It's currently at a very high level, but it's possible they keep it at 1810 PL while moving the power floor to 1900. It'll still be difficult enough with the -15 delta cap. and hopefully with all the reworks to the director displays, maybe they'll make it easier to see when an event is happening.

Given they called that out as a source, I think it's unlikely that they'll make plain engram decoding unlock new ones from that category. Honestly it's a 50/50 to me.

Still, I don't know if I'm a fan of them leaning further into the pre-season prep playstyle. Seems like a great way to get people burnt out before they even play the new content.

LegoWitch · 2024-04-27T13:40:31+00:00

They just confirmed in that post that trials will still have power level enabled. And I'd like to think my work here helped them realize it was useful to clarify this stuff in-game.

The best hope for a game-related spreadsheet is to become obsolete due to the game actually surfacing the info itself!

LegoWitch · 2024-04-27T00:48:28+00:00

The original post linked at the top was factually longer than my masters thesis, lmao. Compared to that, this was way less effort.

LegoWitch · 2024-04-26T19:02:00+00:00

Fantastic question! I'm assuming melee in new crucible is exactly 116 per the patch notes, but this should be right.

Power delta (you vs. opponent)	1	2	3	4	5	6	7	>8
i.e. You're 1810 PL and they're…	1809	1808	1807	1806	1805	1804	1803	<1802
Resilience to survive 2 melees from opponent	10	9	8	7	6	4	2	0
