How many acts are there?

[Nagi]

I just Finisher act 2 and i saw an archivment for finishing act 3 and beating the game.
So my question is, is there another act after 3 or is it also the end?
Cause it feels like iam reaching the end by the fact i nearly got all skills and reward board things.

Spoilers, but yeah, 4 acts, Prologue, Act 1, Act 2, Act 3, and Act 4. 2 is probably the shortest in terms of stuff to do in the main line, but has the most side content, as you just unlocked a lot of stuff. Act 3 is about 3 times as long in terms of its main plot, and contains a few more bits of side content, and Act 4 has only a trickle more side, mostly being the wrap up of the story, and deals with all the revelations and stuff that act 3 gives.

As to the Reward Board, after Act 2 it only has 2 more areas to unlock that are part of it. That does NOT mean those are the only areas to come up after this that you hadn't seen, they just aren't filled with the side stuff that the RB needs to build the bonus objectives, instead being focused areas, either with single paths, or small divergences. Also, some new areas in old places unlock thanks to the interlinked areas of the map.

I kept the question as plain as possible for spoilers.

Thx for the answer, i thought iam close to the end by end of act 2 but its nice i get some more hours of gameplay.
Act 2 took some time but only cause i was doing so many other things. :D

Indeed, it has the most side content of any, as it's the first bit to unlock...well most of the overworld systems and stuff. A good way to do it honestly, as in Act 1 it would have meant asking questions on the mobility of the party, and too much later and you'd be loading it all on the back end.
