0x038C TaggedMessage

One whole client message, under a tag that depends on which message it is.

Opcode	Direction	Verified to
0x038C	client to server	fields

Field	Bits	Encoding	Meaning
Tag	5	unsigned	The tag: 0x03, 0x0B or 0x13. A message of a given opcode always travels under the same tag.
Payload	varies	byte block, 32-bit length, byte-aligned, the length counts itself	One whole message, from the next byte boundary: its own 32-bit length (counting those four bytes), then its 16-bit opcode and its body.

The client sends it before the world as well as in it: at character select, a Client082D goes out inside one under tag 0x13.
