Chance to Hide = (HiS + MS) /2 . This value is checked when you try to hide, and - I believe - once each round you continue to hide. You want this value as high as possible. Move silently gives bonuses after you leave the shadows. In particular, it increases the delay between when you leave the shadows and when you become visible. Hide in Shadows does nothing extra for you. So, forget that Hide in Shadows exists. Put all your points into Move Silently.
Hoooowever, there is a numerical limit on how high you can pump your Move Silently, which is 255%. So if you wish to have a higher Stealth value( say 150%), then some points will be needed in Hide in Shadows.
Pump into Move Silently first though.
Is all this true? If so, what are the other bonuses Move Silently gives after leaving the shadows? Also, about Stealth Value, whats a good amount to have? 150% seems a bit much.
Well... what I've heard about how HiS and MS differ is that Hide is checked when there are no enemies around, and Move Silently is checked when the hidden character is within a hostile creature's range of vision, i.e. it checks either one or the other, depending on the situation.
Elsewhere I've read Hide in Shadows is your chance of getting into stealth to begin with, and Move Silently is checked to see if you remain in stealth. Dunno if it's right, considering what the OP said.
Is that it is snowing only this paradise? The paradise was already Alice's playground.
