Traditional 3.5e methods of handling bigganumbers Kaiju?

[Gavinfoxx]

Hi there, I was wondering what the major 3.5e ways of handling 'bigger numbers than you can handle' Kaiju is. The 'Way above Colossal sized' things with near arbitrary amounts of hit points, saves, constitution, strength, spell resistance, a list of condition immunities a mile long, which also have solid ranged attacks of various sorts? Anyone have any standard or typical methods and tactics?  Or the 'main sets of things to try to see if they are immune to this'?

Reverse gravity followed by a shitload of unresistable damage to see if it can die by HP damage is usually a good start.  Having an insanely high CL/ML helps

it always comes down to Insanely High CL/ML?

[Gavinfoxx]

What are some spells that target obscure things other than hit points, bypass common immunities like ability score damage, that don't care if it has insane Fortitude saves that it doesn't fail even on a one, and work perfectly fine with Assay Spell Resistance/True Casting?

If you're in a situation where you gotta fight something like that, you're either not suppose to fight it because DM's plot, or you're also a "bigganumbers Kaiju" and its just a battle of attrition.

Blinding Glory from Book of Exalted Deeds is pretty great. No save no SR blind everything in 100ft/level from you. Does require evil targets to function but whatevs.

If it really becomes just a punch out, a Retributive Amulet from the same book will keep you on top, splitting all incoming melee damage between you and your attacker.

Dampen Magic from Complete Champion will totally screw any incoming enemy spells by reducing that spell's CL and Save DC by 1+1 for every 6 CL you have above 7. There is no cap on this scaling and since it's variable you could empower that shit. This also reduces straight enhancement bonuses on magic weapons so if you're immune to non-magical damage (*cough*starmantle*cough*), reducing the enhancement bonus to zero through this spell will make your foe's magic weapons useless.

Avasculate is a 7th level spell (3.5, Spell Compendium, p. 19) that simply says ' the subject is reduced to half of its current hit points (rounded down) and stunned for 1 round. On a successful Fortitude saving throw, the subject is not stunned'. It allows a fort save, but that is only for the stun effect. Only Spell Resistance can prevent the halving of current HP and luckily, Spell Resistance can be lowered/overcome by various means.

Do this a couple times and boom, the 'big numbers' Kaiju is....

2,500hp Monster. (Big Numbers Kaiju)
*Avasculate*
1,250hp Monster. (Somewhat Big Numbers Kaiju)
*Avasculate*
625hp Monster. (Kaiju)
*Avasculate*
312hp Monster (Mini-Kaiju)
*Avasculate*
156hp Monster (Just some dude)

Etc., etc.
