I don’t understand how to assess successfully rolling for intervention. The description reads:
Beginning at 10th level, you can call on your deity to intervene on your behalf when your need is great.
Imploring your deity’s aid requires you to use your action. Describe the assistance you seek, and roll percentile dice. If you roll a number equal to or lower than your cleric level, your deity intervenes. The DM chooses the nature of the intervention; the effect of any cleric spell or cleric domain spell would be appropriate.
If your deity intervenes, you can’t use this feature again for 7 days. Otherwise, you can use it again after you finish a long rest.
At 20th level, your call for intervention succeeds automatically, no roll required.
So what actually does a Level 11 Cleric need to roll for success? An 11%?
Correct, you typically roll 2d10, nominating one of the d10s as the first digit of the roll and the other d10 as the second digit.
as per your example, an 11th cleric would need to roll 11% or lower, for this to be successful.
I see. That seems like a weak feature until the cleric reaches level 20. You only go from a 10% chance to a 19% chance over 9 levels of development. Hopefully it can be upgraded to maybe hitting 50% by level 19...
