| Magical thrown weapons return be default now so a boomerang does not do much good beyond 1st level.
With trip, I agree that alone it is too powerful but a lot of people use skill stunts to allow players to make a trip attempts so the bolas could provide a bonus to such actions. Similarly since you are using the Indiana Jones style swing from the banister whip you could give it a bonus to a skill stunt to disarm.
Just some thoughts. I especially like the Shillelagh and I think you did a good job with the longstaff. |
