Missile damage calculation in 4.2.3?

[Bogatyr]

What's the missile damage calculation in 4.2.3? In particular, it seems that the effects of brands have been reduced from earlier versions or are figured in earlier than before?

A (x4) launcher with branded ammo is definitely not doing (x12) damage to vulnerable monsters, seems more like (x7).

E.g., A Light Crossbow of Extra might (x4) (+17,+24) using ammo a bolt of flame (1d6) (+10,+9) reports average damage of 265 at shooting speed 1.0

Interesting that an artifact bow with "weak fire" brand seems to do about the same damage -- is a "weak fire" launcher the same as a non-branded launcher using missile of flame? Meaning "of flame" means something like a 1.5 multiplier?

That's right - the multipliers are added, so its x7.

Weak fire has a +2 multiplier. The missile code picks the better multiplier, so if you had a x4 launched with weak fire brand, you'll get x6 against fire-resistant monsters with regular arrows, and x7 with arrows of flame.

Got it, thanks.

You mean non-fire-resistant?

Yes, that's correct
