Making a Weapon Deal 2x Damage to a New Monster Type

Does it read a normal enemy as a dragon-type enemy? If not, does it read a human-type enemy as dragon-type?

Also, for this line:

Code:

$C2/41DA B9 95 3C    LDA $3C95,y[$7E:3C99]

The value in brackets indicates 3C99, yet the bytes used are 3C95. It is a typo or is the "y" value adding 4? (I'm used to high-level programming languages, ASM is still baffling me, so my apologies if my questions are stupid! )

Finally, about the BIT opcode, there is a flag that targets "bit 6 or 14" specifically, yet there is no info about how to set up that flag
