Summarizing real quick on tablet.

Dragonhide set;
Dragonhide Robin hat
Dragonhide body & chaps
Dragonhide ranger boots

Set should have same aim bonus but increased defence bonus based on dragonhide type
Green 40def, Blue 45 def, Red 55 def, black requiring 60 def with highest def, but lower than rune
Include should be a quiver, acting like a storage and ava atractor,  should not work while wearing chainmail/platebody,
thought about including 1 cast of telegrab runes to make just for lore sake (quiver auto telegrabs arrows) 
Just gotta add dragonhide drops, and into the crafting skill

mystic robes; Blue, Black, Green (guthix cape)
Mystic hat
mystic top & bottom
mytic boots & wizard boot
Mystic set can be bought at mage guild, although possibility to upgrade wizard robes into mystic sound like a good idea

Smithable Metal boots ( allow making of iron- rune boots)

99 dyes for legends cape;
The legends cape is like a blank canvas, image being able to dye it into one's favorite skill,
Requires a 99 to buy a dye from same person who sells legends cape, obviously when the cape is dyed , it'll stay dyed to that skill when any future cape is bought/picked up.
To change look just use a different dye, to remove the look just use a bucket of water(?) Or buy a Legen-dye (needs name changes) to remove dye.
