Spider Monsters for 4e Part 2 - Aranea

After making a new monster for the upcoming adventures in the spider-haunted forest, I thought I'd do a few more. I thought for this one I'd go really old school with a monster I remembered from module X2, Castle Amber. Then I noticed that it had come along for the ride into the 3e monster manual and the SRD, which might make this a bit easier...
Aranea
An aranea is an intelligent, shapechanging spider with sorcerous powers. In its natural form, an aranea resembles a big spider, with a humpbacked body a little bigger than a human torso. It has fanged mandibles like a normal spider. Two small arms, each about 2 feet long, lie below the mandibles. Each arm has a hand with four many-jointed fingers and a double-jointed thumb.

Level 4 Controller
Aranea Webmage
XP 175
Medium natural beast (shapechanger, spider)
Initiative +5 Senses Perception +8; darkvision

AC 18; Fortitude 16, Reflex 17, Will 16
Speed 8, climb 4 (spider climb)
mBite (standard; at-will) * Poison

Change Shape (minor; at-will) * Polymorph
An aranea webmage can alter its physical form to appear as a unique Medium humanoid or a Medium spider-humanoid hybrid (see Change Shape, MM page 280). It loses its bite and web net attacks in humanoid form. It loses its weapon attack in its spider form.

Skills Athletics +7, Perception +8, Stealth +10
Str 11 (+2) Dex 16 (+5) Wis 13 (+3)
Con 14 (+4) Int 15 (+4) Cha 15 (+4)

Aranea Webmage Tactics
An aranea webmage avoids physical combat, using its webs to immobilize targets and employing its psychic bite. In a battle, it tries to immobilize the most aggressive opponents first.

Encounter Groups
Aranea are often encountered with spiders and can also be found leading groups of ettercaps.
Level 4 Encounter (XP 875)
* 1 aranea webmage (level 4 controller)
* 2 ettercap fang guards (level 4 skirmisher)
* 2 deathjump spiders (level 4 skirmisher)
Okay, this one was not nearly as simple as the webby spider. I was thinking about doing a second stat block with a higher level and more spell focused version, but just this one has taken way too long. Maybe tomorrow I'll hit a happy medium...

A good start. Here's my suggestions:

The key traits of the aranea are:
1. Being a lycanthrope-ish creature.
2. Its unique abilities coming from the humanoid transformation (sorcerous powers) rather than the animal transformation. (A spiderwere instead of a werespider.)

The best use of araneas I've seen was in Dungeon 137: "Siege of the Spider Eaters". Most of them lived in a spider lair nearby, but many of them had also infiltrated a nearby pirate village to take advantage of human opportunities. By present day, over a quarter of the village's population were actually aranea in disguise.

Aranea may have a kinship with spiders in their regular form, but their behavior & thought processes are more similar to humans, while their sorcerous abilities make them natural leaders. Aranea are magic-using bandit leaders, village sages, and mysterious woodsland rangers, keeping their spider-laden birthing grounds a secret while venturing into human lands for opportunities and profits. (Kind of like most adventurers.)

Off the bat, I'd suggest making aranea Elites to fit in their sorcerous abilities: make a basic aranea monster without any magic, then add a Class Template (wizard or fey warlock) to it to make it an Elite. Remove the Sleep power (which seems a bit overpowered) & your current build should be perfect for the base monster.

Other suggestions:
-Make its type Medium fey magical beast (shapechanger, spider)
-Increase the dagger's damage to 1d6+2 so it compares to Poison Bite.
-Psychic bite should be until end of next turn, not save ends; dazed is a very powerful condition, especially for an at-will.
-An encounter group that doesn't group them with ettercaps. Aranea are more likely to capture humanoids for ransom to make a profit; ettercaps just want to eat them. Unless your aranea like the taste of human meat, I doubt they'd get along well.

Welcome, mikeulem.

Wow, I wish getting the good start together hadn't burned me out so badly. I really don't want to revisit this thing for a while, but if I do, I'll take your suggestions into account.

I like the "basic no magic"/"elite magic" idea, and I probably would have done something similar if creating just this version hadn't taken three times as long as I intended.

I'm not sold on the fey type or the increased dagger damage (it's supposed to be a suboptimal attack to make the humanoid form weaker, plus a Str 11 creature wielding a dagger does do 1d4 by the PHB), but I think you're probably right about the dazing and the ettercaps.

I probably should have a Lore section, too. I can probably use some of your "behavior & thought processes are more similar to humans" flavor for that.

Maybe the real problem is that they're not intended to be the "creepy spider monster in the haunted woods" that I was needing for my upcoming session. Oh well. Tomorrow's monster should fit right into the woods...
