::: Quick & Dirty :::
Available at: Empaths Guilds (ALL/ANY). Cost: 20,000 coins. No levels for this power. Once only cost. Effect: Surprise lets a vampire enter a "blued" (blocked or overcrowded) square.
::: Detailed Description :::
Surprise is a very simply defined power. You can get into squares with so many pires that they "blue" out, and are normally impassable. When you encounter such a "blocked" square without Surprise you must either go around or use a Scroll of Turning (SoTurn) to "clear" the square.
Since the power of Surprise eliminates the need to use SoTurns, it saves you a great deal of money in the long run. Also, because there is no quest to obtain the power, you save the common immediate costs that one encounters when questing, such as time, purchase of transit or pub drinks or whatever, and there is no blood cost at all.
One note though. It is rare to see it happen, but it is possible for a square to get so full, that even a vampire with Surprise cannot pass into the square. Just in case, carry a few SoTurns with you while you travel.
Obtaining the power at the guild is extremely straight forward. Get into the right square while holding the right amount of money, then click the button to learn the power. Tada. Done.
