New Spell: Permanent Spell Arrow

Gumby Bush · 03-29-2019, 11:28 AM

By default, a spell arrow activates once and is gone.

I am wondering what it would take to make a more resilient spell arrow--one I can reuse (e.g., for enchanting a Sai with--I'd just use Cornucopia if it were actual arrows I was interested in). Multiply base cost for the Spell Arrow Enchantment by 100? Anything reasonable will turn out expensive.

One could, I assume, specify whether it was blank or not if one also knew Blank Spell Arrow.

For Cornucopia to make regular Spell Arrows, cost would be 50*(71*P+10P^2) (assuming $1 an energy point up to the appropriate level)=3550P+500P^2 or 32050*P+500P^2 (for used items at $20/energy point after that level). Spell Arrow has a cash cost of 40P+10P^2 in addition to the energy cost of 30P. If we try to make the permanent spell arrow cost the 'average' of what Cornucopia costs:

(355P+50P^2+3205P+50P^2)/2=(4+x)P+P^2
1780+50P=4+x+P
1776+49P=x
so... P=4 gives us x=1972,
P=1 gives x=1825,
x=2000 sounds close enough (what's a third of a work-year at this point?), so that's a cost of 2000*energy cost of eventual spell in the arrow (roughly 20* for the cost, 100* for permanency, I think, so it sounds right from that perspective, too).

Am I thinking about this well? Am I missing anything? Would you just cap the possible energy in a permanent spell arrow at 2 or 3 and say it's 100*usual?
