For Lakshmi to resurrect, you'd need to pump in 5 limit points. 10 if you want to revive them with full health. Furthermore any that have status effects will only inflict them if 5 Limit points are pumped into them.

Also I suggest since your summons are now Limit moves, you should add another effect to your class trait Divine Summoner. Something like... When using specifically Divine Summon, you can use summons without cost if below half of your Soul stat... Or, summons cost half Limit Points, or.... Yeah you get the deal, just a way for you to be able to use your summons more.
