Best ways to kill a Tier 1 caster without being one

[crizh]

This actually can be slightly amended by asking a different deity for every iteration of a similar question (in that case, it might be even the same question).

Yet more twisting and turning to try and avoid the reality of the table in the PHB.

I'll state, yet again, that if you allow a re-roll every time the caster repeats the same stupid question the table becomes meaningless. Immediately.

Ask the same question 4 or 5 times and you are extremely unlikely to not get the truth the majority of the time.

The table clearly exists. Asking the same question over and over is therefore not going to get you a re-roll.
