With most/all other tournaments switching over to LRB5 I think it's only sensible to move Carnage IV over to the same.
To be clear, Carnage IV is now LRB5 not LRB4.
All other rules are the same - Pro before the tourney, skill progression and star players ARE allowed at their new LRB 5 prices.
Inducements will NOT be used, nor can you buy skills for players.
It is still TR100
The only change is in the number of the rulebook we're using

Let me know if you have questions.
