Question on different specialties

[Isajij]

What do the different specialties actually do for your gladiator do they give him a certain bonus only members of that specialty get?

[BlkTmplr]

They get access to their own talent tree and limited access to the other two.

[BlkTmplr]

Oh, as well as heavy armor for War with access to pikes, medium armor for Theatrics with exotic weapons and light armor for Rage.

[Dainoji]

Your specialty actually means a lot. For starters you have your own skill tree as BlkTmplr pointed out. It also defines what weapons and armor you can use, but a huge thing it does is define what fighting styles you will be able to employ in the arena. For example only Rage gets access to Berserk.
