1) Feint - Thrust ability spends 45% less energy if 2-handed weapon is used. What is "Thrust"? I don't see it anywhere in the talent/ruby grids.
Thrust = Lunge
2) Pebble Wall - I don't see any barrier "effect" nor any indication that it is in effect in the user interface. Before, there used to be a toggle button for it and you'll see an icon near the character portrait.
Stony Resilience is Pebble Wall. You obtain it after completing a certain world mystery (think TT2?)
3) Cruelty - Where is the cruelty toggle button? I don't see it anywhere either.
It's a passive ability that you can turn on and off. Check your spell book. You obtain this after completing a certain world mystery.
4) Fencing master - Does this work on both 1h and 2h weapons?
No, only 1H
