Grapple Hook could be cool, maybe spin an enemy around and they are stunned, similar to grave shackle? Also, I didnt mean brutally kill someone with a cat-o-nine-tail or whip, I meant to trip or to make the enemy fall down, example - hurricane slash.

I would like Axes and Duel-wielding like many said. Also a different multi-shot weapon, like arrows, like the Nest of Bees from Deadliest Warrior, look at those episodes POTCO to find some great weapons!

A new type of sword, maybe?
I'd sure like to get my hands on the Flaming Lance of Doom.
Different explosives to work for grenades,
maybe even Famed grenades or something.
There is only 1 grenade, 1 grenade type, and that alone, 1 grenade.
