As someone that uses spiritism to its fullest extent for taming, traveling and getting back to my dead body - the spell 'Ether Momentum' isn't worth the time it takes to cast. The amount of time it takes to cast the spell does not make up for the small speed increase it gives you for 30 seconds. It should either:
- Be able to cast it while moving
- Increase the duration to two minutes
- Increase the movement speed bonus
