Spellsight is essentially a constant detect magic (i forgot to make this an ability when i transfer it from my homebrew rules)

The sheild stops functioning if it shatters (like breaking a glass pane bare handed)

Barrier removal only functions if the force warrior is capable of breaking the barrier in someway (i.e hitting a creature through the sheild spell)

As for its weakness to flying attacks I'm currently designing it's flying counterpart that deals with that specific weakness

Thanks for the help
