Last scenario players were confronted with a Wendigo that call to his help a Beast Spirit. I was a bit surprised to see them go down very very fast. Of course they didn't plane to go into combat with thoses characters but still, it feel a bit weird.

So I want to ask : Dont materialised spirit have any protection against bullet ? During the game I tried to find some but fail to do so.

Are a lot of the critters in the SR4A book a bit too weak to put beginner player into trouble ? (except dracoform of course).

Spirits have Immunity to Normal Weapons... In this case, the Spirit would have had twice it Force to resist the Damage from the Bullets... If the Bullets do not (before Autofire benefits) penetrate the Spirits armor (After the Total Armor is Modified by Ammo Type), then NO DAMAGE is inflicted...

Keep the Faith

Shadowrun really isn't a game with "end-of-level boss" fights. Numbers make a huge, huge difference. One tough enemy trying to go toe to toe with an entire group of shadowrunners generally will go down quickly.

Unless it's a high enought of force spirit that none of them can harm him, but then it wont ever go down and fill just kill the team so thats not really better

funny enough, the spirit do not need to be that high if the group is not packing magic themselves.

well that depends on what kind of guns their packing, sniper rifles work quite well on anythink up to around force 6-7.
And Thunderstruck obtilarates anythink up to force 13-14

My team of three almost got taken out by a lone wendigo. I was playing the big-ass troll with a big-ass gun. I came around the corner and he influenced me. He told me that the two mages behind me were trying to kill me. So I turned around and suppressed the hallway.

That's how enemies like that can be effective - using some tactics, and not facing down the entire group at once. To be fair, though, the wendigo in the example wasn't planning for a fight to suddenly go down.

I made the same observation a while back: a baseline wendigo will lose the quickdraw contest even to some lowly street gangers...with some spells ready and his Influence power the results look very much different.

Some good wide bursts from a Samurai with an assault rifle or an Ingram White Knight can also work quite well for "typical" spirits, since drastically reducing the Spirit's defense pool can get you an extra net hit or two to help stage up the damage. Tasers and stick and shock are also great options, and it takes a real nasty spirit to shrug off a monowhip.
