Ok, I'm not really a new recruit, but I am to shadow lairs, so I think I can post this here.
Since I reached vanguard I thought: "This game is complete...I quit" Then I thought: "I can't quit! Then I'll miss apocrea!" Then I realized: "Shadow lairs."
So with a new goal on my mind, to gear up for a shadow lair, I set out on an epic quest for shadow lairs. So, here are some of my assumptions that I've made that I'd like to have answered.
Snarbolax is the easiest shadow lair - False
The silvermail is useful in that situation - True
The shadowsun hat is also useful in Snarby - True
Dark Briar Barrage totally pwn beasts - True, but CTR is recommended
In case the silvermail isn't useful, the undead monsters in this level are slow - False
Despite poison, Maskeraith is useful with a piercing harness - True
The gun puppies in Gloaming Wildwoods are replaced with howlitzers - True
Pulsars are the most useful guns against swarm seeds - False
Normal defence is actually good in the Unknown Passage
There are no oilers in Gloaming Wildwoods, and Ash of Agni is therefore still good there - True
Poison can and will kill me and should not be underestimated - True
Advanced orbs of alchemy drop at stratum 3 and 4 - True, but they are more common in stratum 4
Elite orbs drop at stratum 4 and 5 - True, but they are more common in stratum 5
Swarm monsters have no resistance - False, although void slimes are weak to elemental damage
Using an Argent Peacemaker will most certainly trigger wolver burrows, and might piss off teammates
SRJP and SGWW are still easier than SIMF and UFSC (What does the U in UFSC mean anyway?)
Dark retribution is a bad choice in SRJP because of minis - False, while minis are immune to DR, Lichens and Ice Queen aren't.
Biohazard is a good choice against Ice Queen - True
Skolver coat provides the best survival conditions in Frozen Palace even if you're a gunner. - False, provided that you can dodge, Seerus or black kat is better.
There still be lumbers in the Frozen Palace - True
Obsidian carbine is better than biohazard - False, provided that you use swapping to avoid reload.
All shadow lairs are technically T3 - True
Additional notes
Don't fight at traps, gather in a "safe corner" and bottleneck your enemies, probably with the cunning use of breakable blocks and high knockback weapons.
"Shadow Lairs are not so much about the spawn rate as they are about waves." - Bopp. While the rooms are more or less the same as the originals, the battles fought in them are way bigger.
You can change your equipment freely in the Unknown Passage.
Void wolvers doesn't burrow.
Swarm sources are resistant to shadow.
Don't assume that just because snarby was the first boss then SL snarby is also the easiest, imo it's Ice Queen but opinions may differ among people.
Since it seems you're leaning toward gunner I can't help you much, just know that the biggest threats in SL gloaming woods are undeads, not beasts, that doesn't mean tho that you should completely disregard beasts.
