You can't kill the Major Demon's in other people's worlds until you defeat them in yours, since the Blue Stone is inutilized until that parameter has been reached for each specific section

The BP invaded in 3-1, which i thought was a wierd location because he had to run down the prison hall...no room to dodge. He cast warding on himself but apparently that does nothing against magic...so it was just to easy NOT to go after him that way....

Warding only affects direct physical damage, I think he used it as a counter-measure. Do you have any menacing-looking weapon or something of the sort? Many people react by instinct, looking at the other player's equipment xD

I got summoned and started to kill the false king though(didn't beat him though). And I didn't kill him yet.

@Skittles

That's strange, I could never use the Blue Stone on areas that I didn't beat the Major Demon for it. Did you put the Soul Sign in 1-3 or in 1-4?

I finally beat 3-1. The boss was easy compared to the annoying level.

I saved the Sage Freke, but he is not offering me Warding for free like you said he would, lestat. he wants the Dolls Soul.

Should I give it to him or do I need it for later? Also he has other spells that I can learn in exchange for souls. Can I trade them or should I keep them for weapon upgrades?

Put it in 4-2. where the pile of manta's are.(i'm talking about normal bosses, not archdemons lol)

Wait, you put the soul sign in 4-2 and got summoned and defeated the False King? You went between worlds as a Blue Phantom helper? How did you do that? O.O

@marciosmg

It's for free, since you only need to use the Doll's Soul and not pay him extra souls as will happen when you upgrade certain weapons at Blacksmith Ed, in there you'll need the demon's souls and extra souls for him to upgrade ;)

Well, I would exchange the Soul for Warding, it's the single best defensive spell in the game, and it will help you a lot in most boss fights ;)

As for the other souls, you'll need to plan accordingly to what spells/weapons you want to have in your first playthrough, since some souls have 4 different uses, that's why to get the Platinum trophy, people have to play this game at least 4 times.

Here's the list of the demon's souls and their usage, it can help you plan properly ;)

Gah, me messing up the boss names again. >.>
Meant Old hero. lol

Oh, ok xD Even so, i'll try that today or tommorrow, but i'm pretty positive that I couldn't ever be summoned on worlds that I hadn't beat it's proper boss x.x
