How to Anti Idle
Places I've confirmed character will get stuck path finding aka the screen shakes. Sorted by Act.
Act 1 - Outer Cloister
This is very easy to do, however it requires having the outer cloister WP and a char strong enough to kill any monsters that might be in the area. Level 1 mules need not apply.
Act 2 - Stash
Probably the best one to use as all it requires is a char to be in Act 2 and is extremely easy to do.
Act 5 - Stash
Requires a bit of practice to get the alignment and distance right, .e.g. you can't be to close to the edge or to far over. Once you understand the alignments for it not very hard to do.
Act 5 - Town Portals
Another extremely easy one to do. Just go to any area outside of town and make a town portal back, go inside of Malah's shop and then click on the previously made town portal.
