There's a building your team needs to extract a McGuffin from. It has a ward covering it. What do you do?

What I am trying to say is Dual-Natured and infiltration role are like oil and water.

You use your Masking to penetrate the Ward while leaving no traces or alarms that you have done so...

The character DOES have Masking after all...

Do you have a source for Masking allowing you to penetrate wards?

Masking says "Masking: A character who learns masking can change the appear-
ance of her aura/astral form to do the following: look mundane, look
as though her Magic is higher or lower than it is (+/– your grade of
initiation), or look as though she is a different type of astral creature.
When someone attempts to assense the aura of an initiate
using masking, make an Assensing + Intuition Opposed Test
against the initiate’s Intuition + Magic + initiate grade. If they
get fewer hits, they see only the false aura. If they get more hits,
they will see both the illusory aura she provided and her true aura.
To disguise her astral form to look like a spirit or other astral-
ly active creature, the character must be capable of astral projection."

I don't see anything about disguising your aura to look mundane letting you pass through wards. I see nothing under the "passing through barriers" that gives an exception for dual-natured beings who disguise themselves with Masking; they would still have to "press through" the barrier. And per SR4A 194, "Any attack on a mana barrier or attempt to break through is immediately felt by the creator."

If you know of some source for Masking letting someone walk through mana barriers I'd love to know, since I have several characters who would benefit. I do of course think Masking is a necessity for any drake or other dual-natured PC, since it's the only way to not show up as HEY LOOK AT ME $$$$$$ on the astral plane, I just don't think it lets you be an infiltrator.

Fooling Wards
Sometimes a magician just has to get through a ward. Attacking it or pressing through it are viable options (see p. 185, SR4), but both alert the ward’s creator to the action, which the magician may want to avoid. The most covert way of bypassing a ward is to take advantage of the
fact that every ward allows its creator to pass through it freely. If an intruding magician’s aura mimics an aura approved to freely move through the ward, the intruding magician may pass harmlessly through without alerting anyone to the action. Only magicians with the Masking metamagic technique (p. 190, SR4) or spirits with the Aura Masking power (p. 98) may attempt to synchronize their aura with a ward in such a way.

In order to synchronize one’s aura so it mimics a ward’s creator, the synchronizing magician or spirit must be able to see the creator’s aura to use as a reference. One way to do this is to track the astral link present between a ward and its creator (see Astral Tracking, p. 185, SR4). Then an Opposed Test is made between the initiate’s Intuition + Magic + initiate grade and the ward’s Force x 2. If the intruding magician succeeds, the ward no longer inhibits them. If the ward wins, it continues to inhibit the intruding magician, but does not alert its creator until the intruding magician tries to force his way through by another method.

If tracking the ward’s creator through the astral plane isn’t an option (the creator is behind another barrier, the intruding magician doesn’t want to risk being spotted, etc.), the intruding magician can instead use a material, sympathetic, or symbolic link for the synchronization process
(see Material Links, p. 28). Any dice pool penalties incurred by using those links in ritual sorcery also penalize the Opposed Test for fooling the ward.

1) drop magic down to 5, you could geas your adept abilities to still try to keep them all
2) drop athletics group skill level
3) drop infiltration skill level
4) drop hardware skill level
5) drop automatics completely

A drake’s defining ability is to take on the form of a small
dragon, called their dracoform or drake form. While in this form
(and only in this form), the drake gains the following powers: Dual
Natured, Elemental Attack, Enhanced Senses (Hearing, Low-
Light Vision, Smell, Thermographic Sense), Hardened Armor 4,
Mystic Armor 4, and Natural Weapon.

So going through a ward would be as easy as staying in human form

Whoops, I remembered them being like Shifters.

don't know about initiation during chargen, can you get the discounts of using a group + init. ritual?

I think that would be GM dependent, but you would need a contact for your initiation group.

Keep in mind that to sucessfuly mask your way thorough a ward you need to have seen the aura of someone allowed to pass through (the creator or someone he has allowed). That can be a problem if you're in a hurry and the creator isn't anywhere close by. With wards longevity, he may even be on antoher continent...

drop infiltration skill level

Not sure i agree with this. Character has around 12 dice for infiltration, which is his bread and butter as an infiltrator concept. Seems about right to me, unless i'm missing something.
