Diablo II 1.10 Beta Test begins

[Ruvanal]

In normal his skills are
Charge level 5
Jab level 15
...

How many attacks does Jab do? From the sound and watching the life bar it seems like two, but is it three, with the second and third hitting at or about the same time?

Duriels is a 3 attack jab (most others appear to be 2 hit jabs). Duriels sequence is 13 frames long with the attacks on the 4, 10 and 13 frames. Note that it may not play out at the normal rate, I did not dig that deep into the files. (see monseq.txt, I like some of this non-hidden in the DLL stuff)

The quest TCs for the act end bosses have very high chance checks for uniques and sets and then a 100% chance of rare checks (providing the item can be rare).

Hmm, I was going to add to that post that I got a magical Kris from Meph. Do set items downgrade to magic if they fail? Or perhaps a Kris can't be rare!? Also, is that every time you kill the Boss? I thought that Blizzard was going to make them drop much better the first time they were killed only?

Arutha answered the set to magic item downgrade. Ishould have emphasied this more. The act end bosses have some special flags set to note that they are quest canidates and wich quest flags trigger them. When you are the one landing the killing blow and it is settign the appropriate quest flag for you, then these monster will use a different set of TC to drop from.
TC=Duriel for the normal time that you kill them and
TC=Durielq for the quest kills.
It is the bossq TCs that have the enhanced chance of getting the uniques/sets/rares that I described. The other TC that they will normally be using has the same base chances as was in 1.09.

But what were his skill levels? Charge in 1.10 seemed about the same as 1.09, but did Duriel even use Jab before, much less at slvl 15?

From a quick check his skills and their level were the same in 1.09.
