Most teleport spells specify that "you can teleport yourself and your equipment... blah... blah.."...
What exactly is considered "your equipment"? If your character happens to be handcuffed, can the character teleport to freedom? In other words, can you consider the handcuffs as "not part of your equipment"?
...and in a related note, what happens if your character uses a spell like "
Regroup" to summon restricted (ex.: bound by handcuffs, chains, pinned) allies to his side? Are they freed?
