Overhaul Healing Items
If you are a veteran of the Dark Souls trilogy but missed out on playing Demon’s Souls, you might be surprised to learn that there was no Estus mechanic in the game that started it all. Instead, players must use consumable healing items like the Crescent Moon Grass, and its various upgraded forms.
While there is nothing wrong with this system per se, it can be a little annoying. Healing items in Demons Souls can be purchased, but more often than not it is more efficient to farm for them, as you will want to save your souls for leveling your stats instead. This can lead to long and grindy sections of gameplay, which can be satisfying for some, but leaves a lot to be desired.
Introducing the Estus system to the Demons Souls Remake would bring the game more thematically in line with the rest of the series, and would cut down on some of the tedium present in the original. Failing that, perhaps a re-balancing of the drop rates of just the base Crescent Moon grass would go a long way to avoiding this issue.
