While I am not 100% sure where and how to fit this, some players asked for functionalities tied to extracting info from a GUID (mostly for use after a COMBAT_LOG_EVENT - checking the killed unit was a player, his class, race... It would also be useful to extract an NPC ID from a creature kill).

My best guess so far would be to add a GUID dynamic value (like Random is, not a real condition check), as well as condition checks asking for a GUID as argument, allowing for Extended variables. It's probably worth placing as "expert" conditions.

Now that I discovered TRP3_KILL is a thing, it's probably better to update that event so it holds the information by itself (It seems to already extract whether the kill was a player/creature, and the NPC ID). Updating the ticket title to reflect this change.
