Is it possible to change the spell Know-Aura to work similarly to infravision whereas it has a set minimum cast time which isn't specific to INT?

Currently Know-Aura cast length is 1 minutes for my character... which has to stay neutral... which makes it very hard to balance aura without being able to see the current mobs alignment... which is next to impossible since the spell only lasts a few seconds.

I understand that boosting INT would fix this... but adding 18 points to INT just for know-aura is kind of stupid.

Anyways I just figured I would bring it up... I am sure the other Gradius/Ares clerics and other align based classes would thank you as well if this were changed.
