Merge branch 'conveyance_revision' into 'master'

Revise Conveyance

1. slightly reduce the mana cost of Phase Door, it's somewhat too much for a basic mobility talent;
2. remove the 35% failure rate of teleport, increase the mana cost, cooldown and reduce accuracy instead;
3. makes it possible to open vaults while Probability Travel is sustained

btw, makes Body of Stone not break when bumping to attack others.
