intellego aquam question

serfs parma...

I have some characters about to approach a nasty bog that they have to traverse.

If they try to cast a spontaneous intellego aquam spell in order to find a safe route through the various sticky spots, any thoughts on the magnitude they'd have to achieve? I think that "voice of the lake" is too high, since they don't need to converse back and forth with the water spirits.

I was thinking of allowing multiple castings at various junctures, rather than one large casting at the start of the venture.

Thanks in advance.

I would just modify Intuition of the Forest(InHe 10, page 136) with a Aq requisite. It's sun duration

Ah, of course. Silly me. Perfect. Thanks!
