seems to be related to what happens in baal after a whole wave is being killed...
being recived before:
0x2C PlaySound; UnitType: NPC; UID: 1343076052; Sound: BaalLaugh

which is the baal laughing sound when u kill a wave...

no information about a4 packet anywhere and its pretty small (size is 3...)

any1 got any info on it? (its not the same for each wave... and it might be used for other stuff, i just dont know...)

tnx

ok this seems kinda stable..

after u killed wave 0 (cleared the throne...) u get:
1:15:22 PM:627GS: 3    a4 3e 00
1:15:22 PM:627GS: 3    a4 17 00
1:15:22 PM:627GS: 0x2C PlaySound; UnitType: NPC; UID: 3797164611; Sound: BaalLaugh

after u killed wave 1 u get:
1:16:06 PM:188GS: 3    a4 69 00
1:16:06 PM:188GS: 3    a4 7d 01
1:16:06 PM:188GS: 0x2C PlaySound; UnitType: NPC; UID: 3797164611; Sound: BaalLaugh

after u killed wave 2 u get:
1:08:23 PM:193GS: 3    a4 2d 02
1:08:23 PM:193GS: 0x2C PlaySound; UnitType: NPC; UID: 3688764627; Sound: BaalLaugh

after u killed wave 3 u get:
1:09:27 PM:899GS: 3    a4 2e 02
1:09:27 PM:899GS: 0x2C PlaySound; UnitType: NPC; UID: 3688764627; Sound: BaalLaugh

after u killed wave 4 u get:
1:02:33 PM:95GS: 3    a4 3b 02
1:02:33 PM:95GS: 0x2C PlaySound; UnitType: NPC; UID: 1343076052; Sound: BaalLaugh

and after wave 5 u dont seems to be getting a4..

anyway the values after a4 is stable for each wave... checked that for like 4 games (atleast stable for hell...)

0xA4 pretty much has the following format;
[code]
(WORD) Unique ID Code
[/code]
The ID Code tells you the unique NPC ID/Number of the monster being spawned next.
For example, 0x3E/0x17 would be the shamen and fallen thingys, 0x69/0x17D the psn mummys and cold mages, etc etc.

Basicly, in about 5 - 10 seconds from now, baal will spawn an unspecifyed amount of [u]ID Code's[/u].
