How does "resolve powers in the order they're written" work for things like "If you have (elements), +1 Range"?

How does "resolve powers in the order they're written" work for things like "If you have (elements), +1 Range"?

Internal modifiers like this – a Power changing its own Speed, Range, or other targeting – are looked at when they're relevant (like during targeting), not during normal Power resolution. This is an exception to "do things strictly in order once using the Power".
This is also the case for Powers like The Jungle Hungers, where a threshold modifies the instructions earlier in the Power. Technically, every use of "Instead..." in an innate power works this way; it's pretty simple for human minds to understand the intent, but the formal specification is messier.
