Remnant II - All Traits

There are 32 Traits in this game, and all of them can be level up to level 10. There are only 65 trait points you can gather (by collecting Tome of Knowledge, which gives +1 trait point - there is 1 per dungeon, they get respawned when you reroll). By maxing out 2 classes (archetypes), and having them equipped, you will gain 20 points on the traits that comes with the class. When you max out the class and equip another class - the trait from the maxed class carries over, but you need to spend trait points to level it up.

You need 20 traits to unlock all trait-related trophies, but that one is glitched. To unlock it, simply level up either class to level 10 after you get at least 20 traits.

Defeat the enemies near the children, follow them and propmt (talk) to them both. After that, return to Oracle's Refuge and talk to the old lady inside to start the Quil questline and get the trait
• Regrowth - Comes with Summoner Archetype
• Resonance (coop trait) - Get inside the Dormant N'Erudian Facility in N'Erud. Cross the doors at the beginning, and make sure to stay behing with 1 player. The other player needs to find a broken fence and jump down, follow the path and turn on the console at the end of the path. This will kill the player which was left behing, and that player gets the trait. You will have to reroll and retry on your next try with the other player, so that the other player gets it too.
• Revivalist (coop trait) - Teleport to Ward 13, let the other player kill you and revive you 10 times, then do the same to the other player. 
• Rugged - During the Ravager Main Story fraction path in Yaesha there is a chance for The Laemir NPC to spawn in Forgotten Field. He can probably also spawn elsewhere, but I got him here. You will have to battle Root Nexus around him, which also spawns Defiler Elite. By surviving and by talking to him, plus exhausting all options, you will get Reinvigorate Mutator, Rugged Trait, and Laemir Censer amulet (the trait will be yours after just talking to him, after the fight)
• Scholar - Defeat the final boss in the game
• Shadeskin - Finish the burning man event in Butcher's Quarter in Losomn
