I'd love it if they actually spelled it out some. Thats really a pretty vague statement. too vague to get excited about.
Other things- Perception radar. Hmm. On the one hand, I like it as a DC. Its straightforward and you don't have to tell players that they failed a spot check. On the other... if one member of the party has it maxed out (our elf with perception++, high wisdom and the alterness feat), is it an auto-pass for the entire party, or just for him? Does a party with maxed out perception auto-detect everything, and is therefor immune to traps?
Also, acrobatics skill ate the jump skill.
Not entirely convinced that this version of traps will be any better than any other attempt at them, but... it is better than the Tomb of Horrors, 'oh, you made a poor decision based on no information, so you're dead' approach.
And nothing was 'cool', so... progress.
Oh. Good catch on Thievery, Khuxan
Now, hopefully digging a pit will no longer cost 1000+ gp.
