Here is one more for a Dread Warrior (sub-boss) alternative converted from D&D: the Skull Knight.

Movement is only 4 due to low DEX and low speed.

Attack is 4 due to STR mod.

Defend is 1 due to DEX mod (min 1)

BP is 4 due to CON mod

MP is 2 due to INT/WIS/CHA mods

Spells are 3 dread random Dread Spells.

Combined "Life Exchange" and "Tainted Willow" into a single ability called "Vampiric Sword". Removed "Life Exchange" noob trap and just made the sword only equip-able by Undead.
