Serpent Soldier

Serpent Soldier is a hostile NPC found in Sen's Fortress and The Duke's Archives (in the prison)

Description
Tall soldiers, half man, half serpent. Use a huge sword and also carry a shield. Either attack with their sword or try to bite the player.

Drops

 * Man-serpent Greatsword (rare)

Attacks

 * Bite - The raise their head and bite the player. Dos a fair amount of damage but is easy to spot.
 * Forward sword stab - The thrust their sword in a straight line towards the player. Easily dodged, leaving them wide open for attacks.
 * Normal sword sweep - Default attack, sweeps sword from right to left.
 * Heavy sword hit - Lunges out and charges up a heavy hit. Easily dodged and leaving their guard open for several counter attacks.

Weakness

 * Lightning-based attacks do a lot of damage

Strategy

 * Melee - They're rather slow, especially if you circle around them. So either circle and hit or wait for their attack, get behind and backstab. Note that landing several consecutive attacks in a row will stagger them for a short amount of time, so a quick lightning weapon (e.g. a spear) is a good choice.
