#16 - Iron Keep Bonfire
~Light the primal bonfire in Iron Keep~

You will have to defeat the Old Iron King boss and light the primal bonfire in order to get this trophy. To be able to access this boss you will have to have beaten the Dragonslayer at Heide's Tower of Flame in order to talk to Licia of Lindelt and exhaust her dialogue options to get her to return to Majula. The pathway that leads to this boss is:

1. From Mujula, take the stairs down behind the Cat's house.
2. Get Licia of Lindelt to turn the Rotunda to gain access to Huntsman's Copse.
3. Beat the Skeleton Lords boss to gain access to Harvest Valley.
4. Defeat Covetous Demon boss to gain access to Earthen Peak.
5. Defeat Mytha, the Baneful Queen to gain access to the Iron Keep.
6. *Optional but recommended* Defeat Smelter Demon
7. Keep progressing through the Iron Keep to reach the Old Iron King Boss.

As for the actual boss fight, it again is fairly simple. Magic/Lightning/Dark based weapons and spells will deal the most damage to him, ranged spells are the best options to use (Soul Arrows, Lightning, Hexes, etc) or elementally enhanced weapons. You should only physically attack him when he stomps his hands down and leaves them on the platform for about 15 seconds. Otherwise just used ranged attacks to wither his health away as he tries to attack you. Running to the right side behind the wall is a good place to dodge most his fire breath attacks but watch for him charging his hand for a beam attack which will hit you through the wall unless you dodge roll. Video guides for the areas and bosses outlined above are below in order:
