How is expected damage calculated?
Hit chance uses a d20 with natural 1 always missing and natural 20 always hitting. Expected damage blends normal hits and confirmed criticals using average dice results.
Estimate average damage for two weapons against different AC values using Player's Handbook attack and critical hit rules. Edit each weapon like the PC Planner, or load a saved character when signed in.

Yes. The full attack columns sum expected damage for every iterative attack bonus from your BAB, using the same attacker stats for each weapon.
DR reduces the physical portion of weapon damage only. Energy extras such as flaming still apply. Magic weapons bypass DR/magic when the enhancement bonus is at least +1.
When signed in, pick one of your saved PC plans to fill BAB, ability scores, feats, and equipped weapons. You can still edit any field after loading.
No DR applied.
