I tried this calldynamicnpc.
But the problem with this is that only one player can use a dynamic NPC at a time.
If one player called a dynamic NPC, a second player cannot call another dynamic NPC from the same source NPC like I expected.
This cannot call multiple dynamic NPC's from one source.
Thus making it work just like a single NPC with 'cloakonnpc' and 'cloakoffnpc'.
What I need is:
- an NPC/mob that is exclusive to one player
- and players can summon one simultaneously
