Growth (and Shrink) Build Question

[Black Rose]

I am working on these two spells, Enlarge and Shrink. The fiddly bit I'm having trouble quantifying is that, when you get bigger (or smaller), it takes a little while (one Phase per size category, including the "semi" ones from APG 1) and you pay END for each full Size category (costs END to cast the spell first, but then only to change). Por ejemplo:

I go from normal size to Enormous (8m tall, weighs 6,400kg; +30 STR, +10 CON, +10 PRE, yadda yadda). It takes 4 Phases (Semi-Large, Large, Semi-Enormous, then Enormous) and costs 2 END (for Large), and 5 END (for Enormous). The power tops out at Semi-Gargantuan (140 CP; tall enough to see your head and shoulders above the roof of a 10-story building) 

 

I already have Costs END Only To Activate (+1/4) on the build. What would you value the Extra Time and Costs END Per Level Limitations?

I'm thinking a multipower where the slots all have a Limited Power modifier.  

 

Multi, 140 points;  common mods: 

Costs END only to activate

Must be <prior size>;  may only revert to <prior size>  (I'm thinking -1/2)

Extra Time (full phase), only to activate

 

Where that notion of prior size is as per APG 1.  So going to Gigantic...or back to normal from Gigantic...would cost 49 END, altho spread over 8 phases, so there's probably some post-12's in there.

 

Does the power really have to go to those extremes, tho?  Semi-garg is 175 active;  and your attacks are, say, 17-18 dice with AoE radius, so over 20 DCs.  Plus, the nominal complication from the size template, just does not *begin* to express the problems, and the costing is a total joke.  Yes, I loathe Growth.

 

EDIT:  DOH!!!  The MP build feels clean...but the slot costs kill ya.  So 

Growth (up to semi-garg) (140 points) 

Costs END only to change size (same as Shape Shift's "only to change shape") +1/4

Full Phase, only to activate

1 size level shift (larger or smaller) at a time (Limited Power, -1/2)

 

If it's only to grow larger?  -1/4.  To consider:  what happens if Very VERY Big Guy gets KOd, if the "1 shift at a time" applies to getting smaller?  Other than the fact that his falling over is a potentially serious disaster....  Should the reversion to normal size be fast....but if so, perhaps, ALL the END costs might have to be paid?  Ewww.......
