The barriers are very easy to break through, which limits their actual utility
Barrier has a hundred-and-one uses when you view it as a utility spell, rather than as an all-purpose combat defense. It may be the most cast non-attack spell in my game, and most of those casting are not at really high forces. (Granted it may help that I read the spell as saying you can place your wall or dome how you want, not just planted perpendicular to the ground). I’m sure there are threads on this somewhere with more uses listed, but just to get your imagination sparked, here are a few things I can recall it being used for in my game:
- Bridge between nearby building roof tops (and for slightly longer gaps, two barriers, one coming from each side)
- Around someone attacking with shock gloves (stun damage won’t break it) to slow them down (forced them to draw their pistol and shoot through the barrier), which gave time for a spirit to join the fight
- To hold back a swarm of devil rats (that one was edged, for higher armor)
- Just inside a door, the direction that the door opens. Doors do not generally do physical damage, so until something is used that punches through the door, it isn’t opening.
- Alongside a vehicle as it is about to make a turn onto a narrow street. Sure given time the driver could veer away then ram into it, but trying to push against something right beside the vehicle is harder. (another edged roll, to make it stronger) Made the chasing vehicle miss the turn.
- As a work platform on the side of a building—levitated there, but barrier reduced the risk of dropping tools or having bits cut out of the wall falling to the ground and making a ruckus outside of the sustained silence spell)
- To keep a helicopter from taking off (chopper pilot wasn’t willing to risk damage to the rotors)
- To make along drop survivable, by breaking it up a couple of times with barriers
All of that said, unless another character has them covered already, I'd still take levitation and invisibility (and maybe silence) above barrier. Barrier is great utility, while the other ones outright let you do things that let you complete bypass a lot of drek.
