The barrier under the Gargoyle's Maze can be opened without using source. If you liberated Withermoore from his curse earlier in the game and touch the mysterious mechanism with whoever agreed to help him, he will appear to help you through.
That's interesting. I've somehow managed to avoid ever trying that on any of my play-throughs!
This didn't work for me and of course breaking his jar not absorbing it *is* using a source point anyway.
I tried all conversation options for all 4 characters and he didn't turn up. I had previously freed him by pulling out the spear and then freed his soul by breaking his jar. Perhaps something else is required.
It isn't worth it anymore unless you want the gloves anyway I guess.
I'm not sure I like this change as there are only 6 soul jars. Assuming you play nice you break 3 and that only leaves another 3 for the whole first act - not enough to try out source skills really.
