Not every treasure chest is as helpful as it seems. Sometimes, you'll get near one and find that it is actually a dangerous Mimic. Your best bet is to hack apart any chest you find, so that you can get a head start if it winds up having a life meter. However, another trick is to stand nearby, outside of potential striking range. Watch the chest closely for several seconds. If you see any movement, such as an opening and closing lid, that's your cue to get offensive.
Defeating Iudex Gundyr
Iudex Gundyr is the first Boss in the game. He is part of the tutorial section and quite easy to defeat. To start the fight, you must pull a spike out of his chest. Attack him immediately to take away a good chunk of health before he gets up. Approximately halfway through the fight, he will transform and get more aggressive. He is defenseless while transforming. His attacks can be parried with a shield, or simply dodge and try to get behind him. If you play as a sorcerer or pyromancer, keep your distance. You can also use your three estus flasks to refill health. You will get an achievement for defeating each of the eighteen Bosses.
Defeating Soul of Cinder
Soul of Cinder is the final story Boss. After defeating him, you can interact with the last bonfire (same place where you fight him) to trigger the game ending and start New Game+. He uses a variety of attacks and weapons that he is always switching around. A recommended strategy is to take Havel's Greatshield (any greatshield will do) and walk close to him in circles while blocking all attacks. After blocking his combo, attack him 1-2 times and block again. After a few hits, he will get stunned and you can take down a good chunk of his health. Just keep it slow and block, do one hit and repeat. In between his attacks, you should release [Block] so your stamina recovers quicker. When he uses magic, you can get up close to him and just attack. After his first health bar is gone, he gets more aggressive. His available attacks change slightly. He uses longer combos and throws lightning spears at you. When he uses lightning he is vulnerable -- that is when you should attack even if he hits you a few times. Roll away from him when he does the 5-hit sword combo with the big fire explosion. Everything else you can block with the shield. You just have to learn how to balance your stamina for this fight so you have enough to block, but also enough to get one hit in. Keep your equipment load below 70% to speed up stamina recovery. You should definitely put a few points in stamina before this fight.
Easy Uchigatana
If you want the Uchigatana katana, you'll have to defeat the master swordsman who wields it. You'll find him near the top of Firelink Shrine. However, you don't have to fight him fairly. You can ascend carefully to the rooftops and then run along them. You should see the swordsman, running along the base of the wall, hoping to duel. From your vantage point, you can safely take him down with shots from the Soul Arrow spell. Just make sure you don't run out of magic in the process, or you'll have to drop down and finish the job the old-fashioned way.
Finding Untended Graves secret area
To reach the Untended Graves secret area, you must defeat "Oceiros, the Consumed King" Boss. This is relatively late in the game. Oceiros is Boss thirteen of eighteen. There is also a bonfire in the Boss room which you can use to fast travel. Open the door where the Oceiros Boss fight took place and follow the path into the next room. There is a secret wall behind a chest (end of the room). Hit the wall to make it disappear. You can then drop down into the Untended Graves area and will get the "Untended Graves" achievement.

Havel's Armor
Find the Havel NPC in Archdragon Peak. Kill him and he will drop his weapon and a Greatshield. Now, make your way to the bridge located above Farron Keep. There, you should find a set of armor resting next to the stray demon. The armor only appears in that location if you have first killed Havel at Archdragon Peak.
How to Defeat Vordt of The Boreal Valley
Vordt is the Second Boss you will be encountering in Hall Wall of Lothric after Ludex Gundyr. Vordt is a Knight or we can say a fallen knight has
turned into a beast and you must take him down. He has the ability to walk on all fours also wields a mace in one hand.
Taking him down will be easy only if you have the right equipment like you must have an Armor or any item that will boost your frost resistance to
blocking Vordt's ice attacks. Now taking Vordt down should be an easy task, simply stay close to his Rear side and wait for him to swing his attack, once he is done it's time to charge him with your light weight attacks and the roll away from him.
If you manage to drain his 50% of the health which will make him angry and he will start charging attacks 3 times more than normal, then with some ice attacks from his mouth. SO Repeat the same tricks to get behind him, wait for the right moment and then charge with Heavy attacks until you get him down. Once you Defeat him he will drop Soul of Boreal Valley Vordt and 3000 souls.
Infinite Souls (Exploit)
By taking advantage of a special exploit, you can use a Boss Soul and it will remain in your inventory. Thus, you can generate as many as 20,000 souls every 7 seconds or so, just by repeatedly consuming the same Boss Soul. The exploit is valid through at least patch 1.03, but will likely be fixed at some point after that. Before you begin, make sure that you save a copy of your file in case something goes wrong. Then, carefully complete the following steps.
Equip a shield that allows you to parry, such as the starting shield for the Knight class. Place a Boss Soul in your first Quick Item slot and equip all items in any other slots. Place an empty Estus Flask in your first toolbelt slot. With everything set up as indicated above, hold DOWN on the d-pad and be ready to quickly follow the next step indicated in the process. While continuing to hold the DOWN button, parry and then quickly enter the following moves, starting as the shield's position is parallel to your character's shoulder: Strong Attack Left, Use Item, Open Menu, Confirm. You have to time things very specifically, or the process will not work and you'll use up your Boss Soul without the opportunity to exploit it.
If you perform the exploit properly, a confirmation box will appear and your item select option will vanish. You will be able to consume the soul while it remains in your inventory. If you perform the exploit successfully eight times in a minute, that works out to 160,000 souls. If you maintain that rate, it works out to more than nine million souls per hour.
Save Ember for Emergencies
Ember raises your life maximum, and in the process, it restores your life to the higher total. That's always useful, but it's especially useful when you're in a grueling battle with a powerful opponent, such as a boss. Save Ember until those occasions, and put it to use when you need it most. Not only will you gain a max HP boost, but you'll take advantage of some much-needed healing that would otherwise be wasted.
Snuggly the Crow items
Get close to the nest above Firelink Shrine to talk to Snuggly the Crow. He will trade items for specific things that are dropped in her nest with the "Leave" item option in your inventory. Note: You can only do one trade per playthrough, however this resets with each New Game+. Warning: Do not exit the game with an item still resting on the ground before the trade has been completed or you will lose it.

Solaire's Armor
You can unlock armor that looks like the armor Solaire famously wore in the first Dark Souls game by heading to the roof of Firelink Shrine with the proper items in your possession. First, buy the Belltower Key from the Firelink Handmaid, who will require 20,000 souls. Then ascend the tower toward the bridge. From there, you can drop to the roof and find a nest, where a strange voice calls to you. Leave items in the nest and the crow will give you something else in exchange. It's possible to leave several items (only once each) that will award you the pieces of the desired armor. The list below indicates which items you can offer to receive the desired armor pieces.
Homeward Bone - Iron Bracelets.
Lightning Urn - Iron Helm.
Mendicant's Staff - Sunlight Shield.
Seed of a Giant Tree - Iron Leggings.
Siegbrau - Armor of the Sun.

Walls Have Secrets
Don't just blindly trust that things are as they appear in Dark Souls III. Often, you can find what appears to be a wall and it's actually only an illusion. Make sure that you check walls in suspicious places by slashing at them with a weapon, particularly near archways. Sometimes, you'll find a hidden path that is well worth exploring.
