Black Wax: Varying the Spell Components

In D&D Spells require physical ingredients in the ink when a Magic-user or Elf is creating a new spell. It means those glowing antennae on fire beetles are vital when creating a light spell so you stroll off to the caves and get yourself some spell ink ingredients... But what happens when you vary the ingredients?

Basically anything the Dungeon Master wants...but there should be some logic to it. The wizard harvests some white wax from a giant bee hive and creates a spell that churns out a wax minion to do your bidding.

Wax Doll (4th level Magicuser spell)

 Range: 0' 

Duration: 1 turn per level of caster

Effect: creates a wax manakin.

A wax duplicate of the spell caster appears. It can be instructed to undertake a physical labour task lifting up to twenty pounds, walk at the speed 30' (10'), and has hitpoints equal to the spell caster and AC7. Some wizards apply colour spells to their manakins to make them look human.

But... along comes a different spell caster who heard of the Wax Doll spell and he finds Black Wax in his equatorial Giant Bee hive. Black Wax has a sugar content that is stripped of some of its hydrogen leaving the Sugar and Wax black. what can we make from this alternative.

Wax Shadow (4th level Magicuser spell)

 Range: 0'

 Duration: 1 turn per level of caster

Effect: creates a Black wax manakin.

A black wax duplicate of the spell caster appears. Though it can be instructed to undertake a physical labour task lifting up to twenty pounds, walk at the speed 30' (10'), and has hitpoints equal to the spell caster and AC7. Some wizards apply colour spells to their manakins to make them look human. If it makes physical contact with an opponent it feeds on the hydrogen in their water, desicating them for two hit points damage per round. The Manakin also attracts normal and giant rats, feeding off them with physical contact.
