Question regarding Sustain

[DracoSuave]

Effects don't end if the creator of the effect leaves range, by default. For example, if a fighter immobilizes a guy with a Melee weapon range power, if he walks away, the guy is still immobilized.

Sustain only cares about range if it explicitly says so.

And yet it doesn't answer the general question asked by the original poster. One might almost think a one word answer without proof was misleading or something.

The RAW do not say anything directly, like "ignore the range rules when sustaining" or "follow the range rules when sustaining", though the independent rules for RANGE seems obvious enough to me.

Ranged [number]: A ranged power that has a range expressed as a number can be used on a target within the indicated number of squares.

Sustain: If a power has a “Sustain” entry, you can keep that power active by taking a specified type of action (minor, move, or standard) during your turn. The “Sustain” entry tells you if a power has an effect that occurs when you take the action to sustain it. See “Durations,” page 278, for more about sustaining a power.

Sustained Durations: An effect that has a “sustain standard,” a “sustain move,” or a “sustain minor” duration lasts as long as you sustain it. Starting on the turn after you create an effect, you sustain the effect by taking the indicated action: a standard action, a move action, or a minor action. (You can sustain an effect once per turn.) Some effects do something, such as attack, when you sustain them. A power’s description indicates what happens when you sustain it or let it lapse. At the end of your turn, if you haven’t spent the required action to sustain the effect, the effect ends.

YMMV

 

[DracoSuave]

All sustaining does, in and of itself, is permit an effect to continue an extra round.

Nothing inherent in them does, or does not, end an effect outside of range.

In that case, the general rule applies, which is nothing ends an effect because of leaving range, unless explicitly said so.

Agreed.
