What Reaver said.
Whenever you step into the open, take a couple actions to Observe In Detail - for BOTH planes. Remember: most dual-natured beings are predators, they should be alert, aware, and wary 24/7.
Whenever you come under attack from something you can't reach, move to cover ... get yourself somewhere they have to come within melee (or run-and-jump) range of you, so that you can hit back.
When you sleep, don't sleep in the open. Sleep somewhere that LOS is impossible without being in reach of claw-and-fang .... and woe betide the fool who wakes you unexpectedly!
