Alright lets end This contest...
Chain contingency: Spell immunity: illuision, spell immunity : divination, prot from abjuration(or whatever the dispel magic is)
Spell sequencer (the best one): globe of invulnerability, prot from magic weapons, prot from energy (the one that makes you immune to damage spells like abi dalzims)
Now I'm immune to everything you have to diable me(miscast, silence etc... can't come through due to the globe of invulnerability and the spell immunities)
I'm near immune to you damage: prot magic weapons, prot from magical energy
And I cast time stop faster than any of your high-up damage spell.(cause of robe of vecna and amulet of power)
So you cast sanctuary before my timestop? No problem... I cast improved alluctricity and realease 3 firebreaths on your head along with an in-game chain contingency of 3 abi dalzims horrid wilitings...thats a total of 60d10 fire and 60d8 magic damage in your face.

THAT was doing it the hard way
The easy way is to have a chain with 3 abi dalzims
and a sequencer with 3 fire arrows.
