Warlock Eldritch Blast damage - wrong results

[Methes]

EB damage seems bugged. I'm getting lower values than I should according to both wiki and ingame feat description.

I did two sample collections, one at level 7-8 (500+ samples) and one at level 11 (200+ samples).
Both samples do not take critical hits or misses into accounts and they skip resistances/immunities. They also skip cases where elemental damage kills the mob so exotic damage doesn't apply.

First sample should have 2d6 (lvl 1) + 3d6 (lvl 7) + 2d6 (eldritch mastery) damage = 7d6 or 7 to 42 range.

Second sample should have 2d6 (lvl 1) + 5d6 (lvl 11) + 2d6 (eldritch mastery) damage = 9d6 or 9 to 54 range.

In reality they both have less.

First sample should have 2d6 (lvl 1) + 3d6 (lvl 7) + 2d6 (eldritch mastery) damage = 7d6 or 7 to 42 range.

Second sample should have 2d6 (lvl 1) + 5d6 (lvl 11) + 2d6 (eldritch mastery) damage = 9d6 or 9 to 54 range.

In reality they both have less.

Correct formula is:
1) 4d6 (lvl 7) + 2d6 (e,mast) = 6d6.
2) 6d6 (lvl 11) + 2d6 (e.mast) = 8d6.

There is no stacking with previous levels.

However, 6d6 average should be 21.
Similarly, the 8d6 average should be 28.
So even with correct math, your large sample sizes are coming in somewhat low.

There are also some weird 'behind the curtain' additions/reductions that happen, where the main type is added to and the secondary type subtracted from. (You can see this quite clearly in your damage analysis.) Supposedly this was a balance decision, or everyone would use magic damage all the time.

I think the math is still off in this subsystem somewhere, but it's hard to prove client-side other than by what you've done.

I don't think buffing warlock, which is already quite favorable, is probably high on the list, but it does suck a bit if you go all in on blaster warlock, which takes all your feats, to come in something less than you expected.

Starts at 2d6 damage (level 2), increases to 3d6 (level 5) then increases by 1d6 per (Warlock / 2)

NWN rounds up, so looking at total blast damage:
At level 7: 3d6 + (7/2=3.5)1d6 +2d6 = 9d6 = 31.5av
At level 11: 3d6 + (11/2=5.5)1d6 +2d6 = 11d6 = 38.5av

All Eldritch Blast Damage Types EXCEPT Magic and Positive will deal half Magic or Positive and half Elemental Damage.

So, on average you're looking at:
At level 7: 16ele + 16magic
At level 11: 19ele + 19magic

Where are you folks getting these progressions? I think that is part of the problem.

In the way back machine, they gave an early progression to Eldritch Blast for QoL purposes.

- Eldritch Blast: Minimum damage set to 2d6 - QoL for low levels.

So, while it is not this way, if you imagine first and second level as 1d6, the progression proceeds by gaining 1d6 at every odd level.

The actual way it works is, you do not get Eldritch Blast until 2nd level (@ 2d6 damage granted early by exception). You then remain frozen at 2d6 until 5th level. The Eldritch Blast Chart from the level progression on the wiki does a better job of explaining this.

Warlock Eldritch Blast Progression:
1 - X
2 - 2d6
3 - 2d6
4 - 2d6
5 - 3d6
6 - 3d6
7 - 4d6
8 - 4d6
9 - 5d6
10 - 5d6
11 - 6d6...etc.

Eldritch Mastery: +2d6 Blast Damage

The only mystery here is what I would call the "under the hood" formula by which a given blast reduces secondary damage type and adds to the primary damage type, which is nowhere documented but has been referenced by the staff.

Edit: Ah, I see. Dreams, I think you just did some sleepy-time math.
You have 3d6 + (7/2=3.5)1d6 +2d6 = 9d6.
Whereas 6d6 ≠ 9d6.

[Dreams]

Pretty sure I’m right. You multiply inside with outside the brackets:

3d6 + (7/2=3.5)1d6 +2d6 = 9d6.
3d6+4d6+2d6=9d6
If it doesn’t round up the result then it’d be 3+3+2

I got all the info from the wiki article.
