I was thinking of going into the UGW shadow lair, i have a shadow key on me. I asked people in my guild if they wanted to do it, everyone was busy through. However, i changed my mind about it due to my gear. This is my set right now:
Azure Guardian set
Valiance (CTR: low)
Leviathan Blade (DBV: Fiend and Undead, low)
This set i was thinking of using for the shadow lair:
Helm: Shadowsun Stetson
Armor: Deadly Virulisk Suit
Shield: Barbarous Thorn Shield
Sword: Barbarous Thorn Blade
Sword 2#: Glacius/Combuster/Voltedge
Handgun: Blitz Needle/Argent Peacemaker/Polaris
Bomb: Radiant Sun Shards/Shivermist Buster
Feel free to recommend me sets for this shadow lair if this set is not good for it.
There have been many threads on equipment for the Shadow Gloaming Wildwoods; search for them. Also read the wiki page "Shadow Lair", if you haven't.
Your armor looks good, except that the slime bonus on your suit will be wasted. No big deal. BTS is a great shield, because of the piercing protection and sword bonus, but I do feel that shadow protection is a bit more valuable on the shield, due to the howlitzers about.
If you use any swords at all, then you want a piercing sword and an elemental sword; good. You also want either an anti-howlitzer gun (Polaris is good) or a crowd-control bomb (Shivermist is good). You don't need both, but your party needs (wants) both. I've never used RSS there. So in short your equipment looks good. If your party is similarly equipped and decently skilled, then you should have good fortune.
