Calculating Your New Crit Odds with Risky Ring

The formula to calculate your new crit odds becomes:

1 - (1 - (0.05 \times \text{Crit Range}))^2 

This calculates the odds of not rolling a crit in two dice rolls. Below is a table showing how your crit chances varies.

Minimum value for Crit	Chance without Advantage	Chance with Advantage	Two attacks with advantage
8	0.65	0.8775	0.985
9	0.6	0.84	0.9744
10	0.55	0.7975	0.959
11	0.5	0.75	0.9375
12	0.45	0.6975	0.9085
13	0.4	0.64	0.8704
14	0.35	0.5775	0.8215
15	0.3	0.51	0.7599
16	0.25	0.4375	0.6836
17	0.2	0.36	0.5904
18	0.15	0.2775	0.478
19	0.1	0.19	0.3439
20	0.05	0.0975	0.1855

Calculating Your Damage Output

We will be assuming you always hit because we'd need to factor in AC and all your attack mods. With crits being a flat 2x damage, finding average damage is straightforward. If you have a crit rate of 0.5775, you'd essentially be dealing approx 1.5775x damage on average.

FAQ

Why would I use this build?

You get a lot of crits.

How well does this build perform?

No idea, thought it'd be fun to make.

Bugs of Note

1. The build performs better on any character that is not your main toon since you can have them stay at camp and rejoin for Morninglord's Radiance which grants an additional dice, which doubles on crit.
