The axe pendulum thingy in SolA makes Disarm go up quickly. You can just click on it as fast as possible. I got a lot more there just clicking away one night, than I did all the times before, just clicking on it when I noticed it was up.
I'm not sure there is a fast way to raise Sense Traps. Just put it on a commonly used button as others said, so that you're always hitting it. -------------------------
As others said, use the swinging axe trap in SolA and just click on it. You don't have to wait for the button to refresh. Skill ups go very fast.
The axe is in the path as the path winds around the very first windowed room you encounter as you zone in from Lavastorm.
Be careful in attaching sense traps to another hot key, such as backstab. As you know, if you actually sense a trap, you are spun around to face the trap. This can be disconcerting and even life-threatening if you are in the middle of a fight, hit backstab and get spun around to face some other direction. This is particularly relevant for LDoN, in which there are a number of traps.
