"Will you look at that?! The hopeful heroes of Egypt, seem to have run out of luck! Your quest to secure the artifact were all in vain!" says the ghost of the oracle, as it reappears from within the walls.
"You didn't ever stand a chance! The Nemes Headdress grants its wearer powers that you could never hope to match!"
Meanwhile, the mummy is charging towards Feyra, who, (For easy of play), had just successfully disarmed Basmet. The undead Pharaoh bites her shoulder to the bone, inflicting terrible pain. This deals 10 points of damage, and forces Feyra to roll for two fortitude saves.
Basmet will have to roll a will save as normal, until she succeeds. Failure indicates she will use any other weapon she has available, or try to retrieve one, harming herself on subsequent rounds.
Charles has reached a dead end in the corridor, behind the two women adventurers accompanying him (In relation to the mummy's position.)

"No! You will pay for this!" Charles immediately attacks the mummy's head with all his strength since he is angry that it hurt Feyra's shoulder. Charles will use his Khopesh to attack the mummy.
Attack Roll: 25 (20+5=25) - (Critical: 16 {11+5=16})
Out of Character: Yep all of this is natural rolls, do I need to roll for damage?

(A natural 20 is an automatic hit, unless there's concealment involved; no need to add the bonuses there. Likewise, a nat 1 is an auto-miss. Just for clarification, we call "Natural" The die result, before any modifiers are applied to it.)
Yes, any time you roll above a total of 9 in your attack, you should roll for damage. In case of a [Critical Hit] threat, such as this, you roll twice and add up everything together. If your weapon deals 1d6+2, its critical damage is basically 2d6+4.
Feyra screams out of pain from the mummy's bite terrified by it, as she tries to find the courage to stand on her feet for the moment and prepares herselfs defensively.
