Climb and Balance spells

Seeing as we have a Jump spell to help with jump checks, perhaps we could add spells for climbing (like the Spiderclimb spell from PnP), and a balance spell/potion for balance checks (maybe call it Stability)

Wouldn't Spiderclimb work for both? If you can walk up a vertical beam, you should be able to walk across a horizontal one.

well, vertical climbing is different than horizontal walking.... mainly in respect to whether one needs their hands free and available. With the Spiderclimb spell, you need at both hands free to make use of the effect, whether you wish to travel vertically or horizontally.

If you are simply doing a 'balancing act' you could have both hands occupied and still do fine.

For the purposes of NWN, you could use spiderclimb for both, sure... as the main problem with needing both hands free to move is having to defend yourself while doing so... and in NWN you wont be attacked while climbing or balancing....

Due to the fact that in PnP getting attacked while climbing, one would normally lose DEX bonus to AC and spiderclimb negates that penalty, but you still cant effectively attack... but being attacked while balancing you could actually fight back... I see it making more sense to keep them separate, personally.

Mind you, I certainly wont complain if wants to save casters a spell slot
