Both of these used to work in synergy in Vanilla Sil before a certain version, several years ago. After a certain point, half/Scatha decided put a stop to this. So Concentration no longer synergizes with Opportunist

was this considered overpowered? it's deep into two trees that aren't melee/evasion, and the enemy needs to be running away already.

I realized I was thinking of the charge+knockback+opportunistic +/- concentration connection. I might be completely wrong about what I said earlier. My mistake.

That said, solely Concentration + Opportunist alone ISN'T overpowered per se. Because the enemy has to move away every time, you constantly need to move. So, Concentration won't hold because you keep moving. You'd have to say in one place in order for Concentration to keep effect.

Any word on the actual 1.5 release? ~10 days left before Christmas...

Found a probable bug:
Confusion doesn't prevent Veagance from taking effect. Not sure if Fear or Stunned prevents Veagance either. imo, all of these should prevent Veagance to varying degrees

what does "stand fast" do?

"Stand fast" prevents monsters, like Mountain trolls for examples, from doing Knock-Backs to you.

Or cats from exchanging places. Essentially it prevents any modification of the player position from enemy skills that would change their location.

i forgot i asked this question lol
that's actually really useful. knockback breaks concentration chains which is really annoying.
