Honestly, I don't know about models, but here is the idea:
A shadow or ghost boss, in place where the frost dragons would normally be in the relleka slayer cave.
This boss should be a primarily Melle boss, but with the potential to hit well over 40 every once in a while with a magic attack.
This boss should be primarily in "Shadow Forme", where he can not be hit by any attack, and heals himself rapidly.
To remove the shadows shrouding the boss, you can attack it with the shadowblade, which will destroy his shadow barrier, allowing the boss to be hit directly with any attack style.
The boss will revert back into shadow forme every once in a while, maybe every 45 seconds or so, and then would have to be attacked by the shadowblade again.
He must also be able to launch multiple attacks, with multiple targets with the magic attack, (which could use the shadow barrage animations, by the way.)
Possible rare drops: Brawlers (I know, not released yet), High amounts of blood, death or soul runes (50-60), coins (24-40k),x1-3 Noted Uncut dragonstones, or opals, x1 Uncut Onyx, Completed Smoke Dungeon Champion Key?
