In my opinion this ability is a bit overpowered due to the classes that pair up with this weapon type and the combos that can be abused due to it.
It gives tome users an unfair advantage over melee characters since they can book smack someone and push them away with Typhur, which forces them to take damage for one turn since they only have enough momentum for one action.
It also allows mages to trump melee classes in close combat since it takes momentum, giving mages two attacks while allowing the melee class only one attack.

Close combat options for mages are limited but this was not the direction to take since it gives too much power to their close combat ability and it can be paired up with Typhur and be easily abused.

I believe this skill could of worked well on something like axes due to the size and impact of the blow, it would make sense for your opponent to get staggered.
This would give them the choice of fleeing for a turn or staying and fighting at a disadvantage which would be especially devastating for ranged classes.
