^_^ I useto panic in those situations as well. However, it's always easy to get away... however, the worst situation I've been in: Being surrounded by 4 people with spears...... for some reason, no matter how slow they are, you just can't jump over them. They can always knock you to the ground! >_<
... but there's one item that I don't NEED, but I LOVE!
Smoke bomb... I can easily get away without any items (in fact, I practice missions without using anything but a grappling hook) ... but... smoke bombs... they're so addicting to use!!!
