This is my 13th Dark Souls 2: Platinum Trophy Guide!

#13 The Heir (Trophy)
~See the Ending~

After using Ashen Mist Heart to acquire the 4 Soul of a Giant you will be able to challenge the final boss of the game. 3 of them are in the Forest of Fallen Giants and 1 is in the Black Gulch. Below is the path you will need to take to see the ending of the game:

1. Find all 4 Soul of a Giant (See video guide for all 4 location walkthroughs in spoiler)
2. Defeat Throne Watchers
3. Defeat Nashandra.

The only boss you really need to worry about is Nashandra, she can curse you quickly which makes you lose your humanity / health so destroy the hexes she places around herself to prevent being cursed. Watch out for her hand beam attack which deals a lot of damage when you are far away. If she approaches you then she will attack with her Scythe, be aware of that as well. She seems to take damage evenly from everything so use your strongest spells/weapons on her, she is an easy boss in the end. Video guides outlining the walkthrough and bosses are below:
