Tuska abilities

I'm maxed on rs3.

Any point in me getting the abilities? Are any of them actually really good or something I'd feel I missed out on later? thanks.

If you're going to Slay anymore, the ability is basically a 1 hit ko vs. Slayer Task.

Dont see why you wouldn't want any abilities they all have use at some point
