On to what I looked at initially:
NEW MONSTERS:
[sblock]Blightborn Demonthorn - Lvl 11 Controller
Blightborn Thorndrake - Lvl 11 Brute
Blightborn Troglodyte - Lvl 10 Controller (leader)
Blightborn Twig Blight - Lvl 1 minion
Blightborn Thorn Blight - Lvl 11 Minion
Fomorian Dark Initiate - Lvl 13 Solo Controller
Fomorian Dark Master - Lvl 19 Solo Controller
Displacer Beast Nightmare - Lvl 15 Elite Skirmisher
Briar Hag - Lvl 12 Controller
Nothic Gazer - Lvl 11 Artillery
Nothic Stalker - Lvl 11 Skirmisher
Ghost Troll Render - Lvl 13 Brute
Ghost Troll Devourer - Lvl 13 Lurker
Ice Troll - Lvl 10 Soldier
Troll Vinespeaker - Lvl 14 Controller
Will-o-Wisp (as seen on the WotC Site) Llv 10 Lurker.[/sblock]
Want to talk about a few of these.
Blightborn are fey that are "twisted by the darkest aspects of nature, which subtly or dramatically changes them into something evil and unnatural." I dislike "Unnatural" and "Fey" being together, but all right. I do like the Demonthorn creature, although I see an error in its statblock (it's called a mandrake).
The Fomorian solo controllers are dark fey magic users. The masters often create the Displacer Beast Nightmare (a two headed displacer beast) to aid them. These are how controllers should be; two immediate reaction powers (one at will, one encounter), and several options.
[sblock]Ghost trolls are very cool. They are created by rituals, and while insubstantial, they lose their insubstantial status if they take acid, fire or radiant damage. I like the Devourer - it basically bites someone and holds them in its teeth/stomach, restraining them until they save.[/sblock]
New hag, yay!
New Magical Items:
Eladrin Ring of Passage Lvl 14 (coulda sworn I've seen this somewhere)
Life Force Amulet - Lvl 17+ - Nice.
Mordant Weapon - Lvl 8+ - Does poison/acid damage. The daily is a close blast 3, however. Nice.
Torc of Fortune - Lvl 14+ - The daily power isn't worth writing home about, but the Property! Shift 2 when you make a saving throw on your turn.
Sunwrath - Lvl 12 - +3 Longsword, gives a minor encounter power that lets you do fire and radiant damage until the end of your current turn.
[sblock]There's also a nice Eye, can be used as an orb impliment, but is meant for a large spellcaster to put in their eye socket. There's a ritual that you can use with it, that teleports your body to a specified site when you die.
Then there's the Stone Cauldron - a site which acts as a trap until you overcome it, and can use it to return someone as a ghost with the troll's 'you're insubstantial until you take acid/fire/radiant'. The book spells out 'we assume your players won't do this. If they do, institute your own penalties.'[/sblock]
