I have managed to 100% complete the base game and in the process of the final trophies to get platinum. However it has come to my attention that the Full Mastery trophy has not been unlocked for me yet, I am power level 470 and have no DLC.

Please advise on how a base game player is able to unlock mastery without shelling out an addition $30 for DLC. A lot of the other trophies in the base game explicitly make it clear that the trophies are tied to it.
Such as:

Old School Treasure Hunt
Collect 5 Treasure Hoard rewards (Base game only)

Row Rage
Ram and destroy 5 boats in under 2 minutes with your longship (Base game only)

Home Decor
Place an item on each settlement cosmetic spot (Base game only)

Master Hunter
Defeat all Alpha animals (Base game only)

Dreamcatcher
Destroy 10 Curse Symbols (Base game only)

Full Mastery should follow this pattern, and not force players to pay extra to complete trophies tied to the base game. Please help resolve this for me, I am around 90 hours in and really want to platinum this.

Hello LPSv2 thank you for your post.

The Full Mastery Trophy should unlock after unlocking all skill nodes in the base game so far (without DLC). You must make sure the game is fully updated to version 1.5.0 for the trophies to sync.

With every update, more skill nodes and skills can be added to the game, so these new nodes must be attained also. I believe there are currently 535 nodes you must attain for the trophy, in the 1.5.0 version of the game.
