I'm still not seeing the 3-attacks reasoning...
If you read
Two attacks
Hit: ...
Secondary Attack: ...
as: Make 2 primary attacks. If (either | both) hit, make a secondary attack...
I can't find any support for this reading, though I know it's had its adherents.
The 3-attack ruling I find more compelling doesn't hinge the secondary attack off the results of the primary attacks at all. They read it as "Make two primary attacks. If you're wielding the correct weapon, make a secondary attack."
This reading comes by ignoring the indenting, or assuming it has no bearing on the interpretation of the power. Under this reading, the "Weapon:" block is a condition that modifies the
power, rather than a condition that modifies the Hit entry.
So you read the power in sequence:
1. Make two attacks.
2. For each of those attacks that hits, deal damage.
3. If you satisfy the weapon requirement, make a secondary attack.
... for a total of two primary attacks, and a secondary attack that
always occurs if the correct weapon is used.
However, once the indentation is taken into account, as WotC_Logan indicates it must be, we have, instead:
1. Make two attacks.
2. For each of those attacks that hits:
2a. Deal damage, and
2b. If you satisfy the weapon requirement, make a secondary attack.
... for a total of two primary attacks, and two secondary attacks that only occur if a primary attack is successful
and the correct weapon is used.
The difference between these two readings is the matter of a little bit of whitespace, so I can easily see how either can be arrived at. The other readings - two attacks which includes the secondary attack, or three attacks where the secondary attack is dependent on at least one primary attack hitting - require one to modify, misread, or ignore the text...
