There are a lot of factors to consider when choosing a buff for Dark Souls 3. One of the most important is the player’s overall health and mana pool. A buff that increases health or mana can be very beneficial, but it also depends on the player’s character’s build and playstyle. One option that is often recommended for Dark Souls 3 players is sacred oath. This buff increases your maximum health by 25%, and your maximum mana by 25%. It can be very helpful in cases where you need to survive long periods of combat without being able to heal yourself. Another option that is often recommended for Dark Souls 3 players is deep protection. This buff increases your maximum health by 50%, and your maximum mana by 50%. It can be very helpful in cases where you need to survive long periods of combat without being able to heal yourself or cast spells. Ultimately, it is important to choose the right buff for your specific playstyle and character. If you are looking for a Buff that will increase your overall health or mana pool, sacred oath may be the best choice; if you are looking for a Buff that will increase your maximum health or damage, deep protection may be the better choice.
