Rarely, a lamia of great divine power undergoes an unholy and dramatic transformation, increasing in size and speed to become a truly intimidating foe. Manipulators and slavers, spiritual leaders and oppressive tyrants, lamia harridans are megalomaniacal, corrupt, and brutal. Only Large-sized lamias (or rarely, lamia matriarchs— but never kuchrimas or hungerers) who are at least 10th level in a class that grants divine spellcasting can gain the benefits of this template. A lamia harridan retains all of the base creature's statistics and abilities except as noted here. Note that all bonuses and penalties associated with changing size are incorporated into the rules below.
CR: Same as the base creature +1.
Size: Increase from Large to Huge.
AC: Size penalty to AC becomes –2, but natural armor increases by +3.
Attacks: Size penalty on attack rolls becomes –2. Increase base claw damage to 1d6.
Special Attacks: A lamia harridan gains the pounce ability and drains 1d8 points of Wisdom each time she hits with her touch attack. When a lamia harridan uses her pounce ability, she also gains a rake attack with her two hind claws (these attacks are identical in other regards to her normal claw attacks). The lamia harridan's caster level for her spell-like abilities increases to match her divine spellcasting class level.
Abilities: Apply the following size modifiers as a result of growing from Large to Huge: +8 Str, +4 Con. A lamia harridan suffers no penalty to Dex from becoming Huge, and in fact gains +4 Dex. She gains +2 Wis and +2 Cha.
