Summoned Dust Mephit

[Egon the Monkey]

This has 10 STR and 18 Dex, but doesn't have Weapon finesse so it can hit anything with its creature weapon.

Sounds like a feature not a bug. Mephits aren't known to be combative terrors but are known to be damn annoying and hard to hit!

Or as messengers. They're meant as suicide letters of sorts out in the planes hehe. There is an entire mephit code written around them, with different mephit types meaning different things when you send them to someone, or the quantity of a certain type. A dust mephit represents a subtle threat, hinting that the sender knows of some sort of plot the recipient has against them. Pretty funny, really, how stronger planars push them around as commodities. Aaaand this is totally off topic anyway so turning nerd mode off.

[Egon the Monkey]

It's a L2 summon, but pretty weak in comparison to others of the same level. It's not bad defensively or with its few bolts, but most L1 summons seem to outclass it. With only 10 STR, being able to hit something wouldn't be a gamebreaker, but would make gang-up attacks with them actually useful.

Mephits are often sent by Lower Planar spellcasters, fiends and powermongers of Sigil to their enemies to convey messages. The variety and quantity of mephits sent relays the message in the form of an ancient code, the dark of which is laid bare below. The recipients of such mephit messages are free to do what they will with the elemental creatures; keep them, enslave them, or destroy them; the meaning's the same. Mephits are never sent to friends or allies, as anyone who's ever met a mephit understands.

Air
A warning to beware, for the giver intends to surprise the recipient with an ambush or political treachery. This gift is usually timed to arrive when it's already too late to prevent the inevitable. Lower Planar diplomats fear the sudden breezes in their rooms caused when an air mephit appears.

Ash
A rude message that the giver doesn't even think the recipient is worth corresponding with any more. Often sent by someone who wants the last word in an exchange.

Dust
This gift represents a subtle threat, with the connotation that shows that the sender has recognised some plot of the recipient against him.

Earth

A sign that the giver will not concede to demands; a stubborn answer of 'No!' to a request.

Fire
Displeasure at an enemy's actions, ranging from disapproval to downright fury depending upon how many mephits are sent.

Ice
The recipient is forbidden to enter the giver's home. This can include Realm, Layer or even Plane, at the giver's discression. The more ice mephits that are sent, the harsher the punishment for breaking this restriction will be.

Lightning
A warning to the recipient to reconsider tactics, as the giver has a hidden ally who can swing matters. This often turns out to be a hollow threat, so the sender is either sure of himself and his ally, or bluffing.

Magma
A gift of gloating, when the giver has bested the recipient at some intellectual or diplomatic challenge.

Mineral
Signifies a willingness to compromise on some point and a corresponding exchange of power or lands. A request for more direct communication.

Mist
A mysterious warning that someone close to the recipient is an assassin. This message is used to encourage paranoia and insecurity between the recipient and his allies.

Ooze
A sarcastic gift, sent by a spellcaster who is sure the recipient is far weaker than he. Often this gift is insulting enough to goad the recipient into making a mistake.

Radiant
Request for a truce; in effect the 'white flag' of mephit messages.

Salt
A blatant declaration of open warfare.

Shadow
An enemy of the recipient has discovered his plans, has subverted and is now manipulating them to his own ends. For a fiend, it's one of the most feared messages, because they never can tell which of their many enemies, and which of their many plans and schemes this concerns. This make a lot of recipients nervous, paranoid, and generally makes them change plans or make mistakes. The shadow mephit can, of course, be used for bluffing, but it's seldom done, for the senders fear that if this rare mephit is used too often, it will be taken for bluffs too much, and then won't be useful as bluffs.

Getting off topic here...
My point is they are pretty weak for an elemental L2 summons, compared to a L2 Water Ele, Fire Ele or Air Ele, all of which have Elementals not Mephits for L1 and 2. This is all down to lack of a feat, looks like oversight, thus bug.
