Complete Nine Realms in Bloom favour.

In Midgard, The Forbidden Sands area, southwest corner. You can find a climbing ledge there, but do not climb, instead go left and pick up the flower 1/9 from the floor at the end. This starts the favour, you can now find the rest of the flowers. Full list and details can be found under the next topic, or in the correspoding collectibles topic of individual realm.

God of War: Ragnarok - Nine Realms in Bloom (All Flower Locations)

This refers to Lore collectibles. There is a LOT to be found across all realms. Only the lores that count towards realm % counts, so you can track that via map overview inside each realm. Check the realm collectible topics for details and videos how to find them all.

This refers to Artefact collectibles. There is a LOT to be found across all realms. Only the artefacts that count towards realm % counts, so you can track that via map overview inside each realm. Check the realm collectible topics for details and videos how to find them all.

As soon as you equip Yggdrasil Amulet, you can use enchantments and equip them in slots for it. Simply equip one to unlock the trophy.

This will happen naturally when you work your way towards Ready for Commitment trophy (upgrading an armour set to its max level).

This one got unlocked for me when you close the first Hell Tear gate. It will happen during the story when Atreus reunites with Kratos at Sindri's home realm.

Apples and Horns are a reward from Nornir chests. There are more Nornir chest than Apples and Horns, so you can even miss out on some. You can find all collectibles for all realms in corresponding realm collectible topics.

Early in the game you will have to purchase a Skill using the earned EXP. Simply open your menu and follow the tutorial when the game introduces buying Skills - and buy one to unlock this trophy.

Bear will be your first story boss, so this trophy will unlock automatically. 

Bear is not hard, just dodge or block his moves, and dodge critial (red glowing circle) moves as they cannot be blocked. This fight will serve as a game tutorial in a way, and it shouldn't be that hard.

The God of Thunder is your second in-game boss fight, so this trophy cannot be missed.

Thor is a bit harder than Bear, and you have to dodge more. After you dodge try to attack and continue with few more attacks if he staggers, otherwise be patient and avoid what you can. You will have to go through 2 phases, both quite easy.

There are 6 Shield to be found, nothing is missable except maybe the Onslaught Shield. That last shield is not counted towards overal Helheim completion %, but it's needed for the trophy. If you miss it, you can buy from the blacksmith shop.

God of War: Ragnarok - All Shield Locations

Sword Hilts and Relics are usually a story drop, or you need to finish a certain favour/open a certain chest. Some can even be found on ground, or in places that are not tied to overal completion %. It's a bit tricky to find them all without the pointers. Note that only Relics counts for this trophy, which is a bit misleading.

God of War: Ragnarok - All Relics and Sword Hilts

You will need Dragon Claw x1, Dragon Tooth x22 to craft all 3 pieces for this armor set. You get these items when you kill big lizzard mini-boss or boss enemies (Drekis), which are usually part of some favours or even story progress. By the time you finish the game you should have some of the mentioned items, and if you still miss some you can do "The Desert Door", "Freya's Missing Peace" favour. I had enough to fully upgrade all armour pieces, minus the one piece I was missing.

The moment when I was able to craft it was then I discovered The Plains area in Vanaheim.

You will need to find all Yggdrasil Amulet Fragments to fully upgrade the Amulet. Amulet is obtained during the story.

You need to visit Sindri's House and talk to squirrel to initiate the favour. You now need to find 4 Stags. Return to The Plains in Vanaheim to get the first one, and we need to find others as well.

God of War: Ragnarok - Favours Guide

There are 15 Trials. First, you need to find 2 Muspelheim Seeds in Svartalfheim to unlock The Crucible gateway in Muspelheim. Then you will need to beat challenges. All the details you need can be found under the next topic:

God of War: Ragnarok - Muspelheim Collectibles

The easiest way is to leave resources for the end without upgrading anything, and then take the weakest armour set to fully upgrade it. You can even save before and when you unlock the trophy just reload the save to save resources. Some resources can be found in Muspelheim area and these can be farmed by repeating the challenges. The rest is obtained throughout the game while doing certain favours and simply beating the game. You should have plenty for upgrading couple of armour sets after you clear everything.

Gleaming, Shinning, Sparkling Crystals can be found by throwing yellow crystals (destroy them in Vanaheim - Norhtern regions and pick them up) in the Wishing Well pond at the bottom in the middle to get it. That cannot be obtained any other way, and you will need them to upgrade your Waist Armour to the last level.

*Wishing Well*
1:56:38 - 3 Weapon Hilts: Runic Hailstone Knob, Pommels of Burning Unity, Hind of Volatile Might, and Crystal armour upgrade resources

Automatic story-related trophy.

King Hrolf is the last Berseker Gravestone and it will appear in Midgard, King's Grave after you cleared all other gravestones. This is where you get the key item to tackle these challenges during the story, and the gravestones are all over the place, basically in all realms. You can refer to the collectibles guide of each region and simply search the term to find them.

1:10:32 - Berserkers Gravestones 1/1 - King Hrolf Kraki (Last one, unlocked after beating all others)

Gna is a valkyrie and can be found in Muspelheim. From the middle area in The Crucible crawn under a rock and follow the path to the area and pick up a book from the floor. This will initiate the toughest battle in the game. It's all about the moves, so learn her patterns and it should be doable. I was doing this after beating the game, after I did everything else, otherwise it could be tough. Also, you can lower the difficulty if you wish.

1:04:55 - Defend your Valour 1/1 (Defeat Gna "The True Queen" trophy)
