I'm going to have Anglon drop Desecrate. With that I can raise up to 40 HD with a single casting (I'm going to need it for these templates…)
I'm going to use up a scroll of Animate Dead on this, casting Blood Money before hand to pay for the material component cost with Str damage.
A casting of Restore Corpse from my wand puts the tree back together. Rubbing it down with Unguent of Timelessness and some pre-prepared alchemical hardening agents will keep it from decomposing. I cast Haste during the ritual as the requirement for the Relentless template.
Finally, I raise a Relentless Alchemical Zombie Scythe Tree.
Zombie HP: 15d8 + 17 ⇒ (4, 5, 1, 6, 6, 3, 5, 7, 2, 7, 1, 8, 2, 3, 1) + 17 = 78
Slashing Damage: 1d6 ⇒ 6
I am now down scrolls of Animate Dead and Blood Money, a casting of Haste and Mythic Command Undead, 2 points of Strength and 6 HP.
