More good reasons that the magic item pricing rules are messed up!
Anyway, what about the ring of protection? It sounds reasonable for the Child's CR.
A standard 10th-level NPC (i.e. one who matches our kid's CR 10) has Gear Value of 12,000 gp. That's enough for both +2
ring of protection (8,000 gp) and
+2 bracers of armor (4,000 gp).
Which'll give the Screaming Child an AC 20.
That seems too high, since the original Child had the lowest AC of all the Seven Sword (AC 10+1) with the Veiled Maidens second at AC 8.
I'd prefer to keep the Armour Class near the current 16.
We could drop the Int bonus dodge bonus from The Child's Martial Artistry to give it AC 17 or give it some other item.
Now, the original monster possessed "two doses of
sand of time which slows a foe for 2-8 rounds", so we could do something with that.
A
wand of slow maybe? That's 11,250 gp for a 5th-level wand so is within budget. I'm not keen on inventing a new
sands of slowness magic item for this conversion!
It's already got plenty of disabling spells though with better save DCs than
slow, such as DC 19
stinking cloud.
Or we could come up with something else. 12k in gold is enough for a decent utility Wondrous Items like a
medallion of thought and
glove of storing or a Rod - either a
rod of cancellation or a
metamagic rod of Enlarge, Extend or Silent. Alternatively, instead of protection we could make the Ring either
improved jumping or
minor energy resistance.
You know, a
ring of improved jumping is tempting. It's already got Tumbling but the low Strength and modest SPs prompted me not to give The Child and SPs in Jump.
That'd give it Jump +11 including the Str modifier plus Tumble synergy.
Let me think…
After consideration, I would prefer a few doses of
dust of disappearance since the original monster had the
chameleon spell which as been lost in our conversion and the encounter description says "He has cast
chameleon on himself and is difficult to see."
While that might be an argument for just giving it
greater invisibility instead of
black tentacles and
shout, it also says it casts spells while camouflaged.
Hmm… I'd rather give it
scrolls of greater invisibility (100 gp per CL each) or doses of
dust of disappearance (3,500 gp apiece) plus something else?
We'd want to tweak the Tactics to say the Child'll use the
dust and/or scroll to turn invisible before attacking.
How about two
scrolls of greater invisibility (CL 9th) for 1,800 gp plus a
ring of improved jumping for 10,000 gp?
The Child has the Scribe Scroll feat, so if necessary we can mentally "handwave" that it makes the scrolls itself.
