just my opinion but potion of energy shielding should be nerfed a bit . let's say +50 energy resistance and only +5 bonus to all saves .
Currently, this potion make you really almost invincible even it is balanced by the fact that with revisited store component, we hace access to only 5 or 6 potions...
I would have prefer to have potions/ammunitions in illimited quantity in store : the price is already here to limit access to these items .
But yes, I use rogue rebalancing component making impossible to steal in store.
