GothikOrk: Is there any penalty for keeping search mode on? I know you can switch it on and off, but considering how useful it can be, I don't know why you wouldn't keep it on constantly, does anyone know?
The search mode works in conjunction with Senses - a Ranger has pretty high Senses and a Scouting ability from the commencement of a new game. A high Senses rating allows a character to see enemies earlier (including camouflaged ones) and also to spot hidden items, identify traps etc. From this, I would anticipate that keeping search mode on will not have a penalty as searching has an integral, in game association with Senses and Scouting.
Being able to spot enemies early is very useful at the start of the game when you have left the Monastery and are weak, so if (as I suspect) you find keeping search mode on helps assist with spotting foes more quickly, that can only be good news.
I will admit I do turn search mode off, but that's because as a party develops their Senses tend to be increased (Senses help with achieving critical hits also) and they spot stuff, enemies etc., without it being switched on.
I hope this helps :)
