Weapon power clause structure

[HexZyle]

I've found the clause structure for weapon powers a little confusing, due to the use of semicolons in contrast with periods. Here are some examples.

Sawtooth Saber wrote:

For your combat check, reveal to use Strength, Acrobatics, or Melee + 1d6+2; if this is not the first combat check to defeat the bane this encounter, add 1d8. If proficient, you may additionally discard to add another 1d8+#.

Can Sawtooth Sabre be discarded on the first combat check for the 1d8+#? Or does all three criteria (not first combat, proficient, did discard) have to be fulfilled to receive that final clause that gives 1d8+#?

For your combat check, reveal to use Strength or Melee + 1d6+3; against an Aberration bane, add another 1d8. If proficient, you may additionally discard to add another 1d8. If proficient, any die rolled on this check shows 1, count it as a 6.

The use of "additionally" leads me to believe that the sentences describing discarding to add 1d8, and turning 1s into 6s only can be played against an Aberration bane. Does each sentence contain its own trigger or does the sequence of the power terminate as soon as at any point a condition isn't met? (i.e. so if you didn't discard, you wouldn't turn 1s to 6s)

Semicolons join the parts that should go together, periods separate powers that should be checked, well, separately. :)

Sawtooth Saber:
If you are proficient, you can play it on
First combat check: reveal S/A/M+1d6+2, discard S/A/M+1d6+1d8+#+2
Another combat check: reveal S/A/M+1d6+1d8+2, discard S/A/M+1d6+2d8+#+2
If you are not proficient, you cannot discard it and only the reveal part applies.

Horrorbane Heavy Pick:
Reveal uses S/M+1d6+3
Reveal against Aberration uses S/M+1d6+1d8+3
If proficient, you may discard (regardless of bane type) for 1d8.
If any die shows 1 (regardless of bane type), it counts as 6.

(It's consistency with other similar weapons and powers - see Scythe and Vicious Scythe that both transform 10s into 12s: would you think that because this weapon is good against Aberrations makes it less capable than a non-magical weapon? Granted, Heavy Pick is pre-Core - that's why I mentioned scythes)
