Play around with it, see how it works for you. Start your day with two 16 ounce glasses of water, before coffee or breakfast and drink plenty during the day. Drink a glass before lunch, and ditto before dinner. A gallon is certainly not too much, and again, if you live in a hot humid climate, it may not be enough. I have lived in both Texas - hot or hot and humid - and Minnesota - very cold but dry cold - and found that people did not drink enough water.
Players may also burn certain items in Bonfires to achieve effects. Bonfires serve as access points for Item Box drops. Due to the lack of a pause feature in Dark Souls 2, Bonfires are an integral point for players to take a break from play.
There is really no magic to speak of in Bloodborne, so if you were a heavy magic user in Demon's Souls and Dark Souls, you'll need to quickly brush up on your melee combat. There's also little in the way of effective ranged weapons. There are just six character stats to upgrade. 2  And, walking back a change from Dark Souls 2, it appears you can no longer respec your character. 3  There's no more equip weight, so you don't have the option to play as either a heavily armored tank or a nimble ninja.
