This is the first game I have GMed and this game has been going on for some time (with house rules to allow progression past lv20). The players have now figured out that they will eventually face the mighty Tarrasque. One of the players (a necromancer) has let slip an ingenious plan to defeat the beast and I am unsure how to deal with that when it comes up.
The wizard in question plans to use a 750gp onyx and the animate dead spell to raise and control the 30HD Tarrasque. This is supposed to be an unstoppable beast but as far as I can tell all they need to do is smack it hard enough and then they control a Zombie Tarrasque. At 4HD per CL the Necromance is more than able to control a 30HD beast.
But, how does that play out against the regenerate ability?
Regeneration (Ex) No form of attack can suppress the tarrasque's regeneration—it regenerates even if disintegrated or slain by a death effect. If the tarrasque fails a save against an effect that would kill it instantly, it rises from death 3 rounds later with 1 hit point if no further damage is inflicted upon its remains. It can be banished or otherwise transported as a means to save a region, but the method to truly kill it has yet to be discovered.
As far as I can tell I only have a few options as GM:
- Congratulations, you now own a Zombie Tarrasque, for home work you can stat that thing up.
- The zombie drops HP at the rate of 40 a round, until you run out of repair undead, it dies, and then the tarrasque comes back.
- Not bring the beast into play at all (not a great option).
