Dark Souls Remastered | Defeating Hydra boss (mini-boss)

The Hydra in Dark Souls is a multi-headed serpent boss found in Darkroot Basin and Ash Lake. It's more of a mini-boss since there is no fog gate, cutscene, or boss music. The boss is not necessary to beat the game, but is the first step necessary if you want to do the Artorias of the Abyss DLC, which is the only DLC of Dark Souls and Dark Souls Remastered.
