It is possible to clip through the barriers in the Sanctum using the rogue Shift skill.
It doesn’t happen all the time, but collision is missed enough times to enable a rogue to skip a good deal of the need to switch to a different era on both levels of the Sanctum.
Yip… Reported previously so its a known issue… The movement skills (Shift, Lunge etc) all have the bug that currently allows them to clip through walls/barriers if used in a particular way… Normally its just clipping through walls if you get the angle right but the most recent problem is bypassing the barriers in the Sanctum.
