Reliable An Immediate Interrupts

[Samir]

The rule is not 'did not hit anyone.'

The rule is 'missed all your targets.'

No targets = no misses.

This is partially incorrect. The rule per errata is "don't hit."

Reliable: If you don’t hit when using a reliable
power, you don’t expend the use of that power.

Thus, if your reliable power is invalidated, you don't hit, so it's not expended.

However, PHB2 and PHB3 use the old, pre-errata "miss every target" wording.

If you miss every target when using a reliable power,
you don’t expend the use of that power.

Since there is a wording discrepancy, I'd say it's DM's discretion.

I know that if an interrupt invalidates an action, the action is lost. However, is the power activated by that lost action (reliable or otherwise) expended?

I think a non-reliable power would be expended.

The rule is not 'did not hit anyone.'

The rule is 'missed all your targets.'

No targets = no misses.

If there are no targets and no misses... you missed 0 of 0 targets, which arguably satisfies "missed all your targets". Close enough to fall within DM discretion, at least.

You missed all your targets (the set of targets you did not miss is the null set) hit all your targets, turned all your targets into ponies, and danced on all your targets heads.

That would make PHB3 the most recent printing. The errata predates PHB2.

And the PHB1 wording isn't the same:

Reliable: If you miss when using a reliable power, you don’t expend the use of that power

PHB 2 and 3 cleaned it up even further-- if you have a power that does not make an attack roll, and an epic destiny that can give that power the 'reliable' keyword, 'not hitting any target' isn't good enough; you'd always not expend that power. Rain of Steel, for example, would LOVE the reliable keyword under the errata'd PHB1 wording (which was errata'd before PHB2).

However, PHB3's wording 1) replaces PHB1's by its own text, and 2) forces you to require a miss in order to do so.

Remember, when dealing with keyword definitions, PHB2 explicitly overrules PHB1.
