This is a very simple mod. This adds certain special abilities to the special units of Caelum theme Return of the Raptors. The Raven Guard gets stealth 20, Harab Seraph gets Stealth 20 and abilities of a spy, and Harab Elder gets Stealth 30 and abilities of an assassin. I changed their descriptions and gold costs to accord this. However, I based the changes on the Complete version of the RotR, so Raven Guard with stealth costs 13 gp instead of 17 the unmodded (by this or by the Complete series) costs.
Harab Seraph now costs 110 gp instead of 90, and Harab Elder costs 280 gp instead of 270. Harab Seraph becomes quite expensive for its abilities as a mage, but stealth 20, ability to lead 25 stealthy fliers (and/or 20 Fiends of Darkness if you can get them) should make up for it. Harab Elder was already quite expensive, so I upped its price only by 10 gp. While probably quite an effective assassin, they aren't common or cheap enough to really benefit of their ability to assassinate.
If anyone can think of a use to the graphics used in the banner, be welcome to contact me. I'm beginning to be quite proud of my MS Paint skills...
It is a Raven Guard with the Cloak from the Stealthy icon in-game, with the cloak continued to cover its legs and the weapons slightly edited.
