I tested BD on high rate server and when I used medusa it was the same effect liek anchor however i did no damage. Is this a bug or is it meant to be like this? No damage recevied during medusa?

It's how it works. ^^

Paralyze and make the opponent immune to damage.
However, you could land a DoT before try to petrify it, and the DoT will continue causing damage.
Like Decay, poison, bleed...

I also notice that when I use that skill medusa theirs no damage have been shown, but I just ignore it. I actually know now the effect of that kind of skill and its really great skill at all. I'll use it during my PVP time.

The skill was made to protect your party members, when they're low of health and can't heal themselves.

The skill was made to petrify your enemies, not to defend.
When someone in your party has it, just '3333' and cardi will purify him.

I didn't said that you'll use it against your party members. They're low of health, no healers near. Then you try to petrify your enemies, you'll not kill then, but then will not kill you or you comrades.

dont forget that no curse has 100% landing rate
that means medusa may be resisted by all the targets in range or only by SOME
wich makes enemies lines weaker
imagine the 3 dds are not affected but the rest of the dd and the healer are petrified..

Ofcourse that every curse like song of silence/medusa doesn't have 100% chance to land.
It still does worth it. For example one of our heroes at siege sunday got medusa while he casted valor. So no more valor for us.
If healer gets medusa/anchor and you don't have any other healer in your party or even if you have if he's not a bish or SE, then say on ally '333'. Eventually someone will purify you or if not, you just have to wait.

what does 333 stand for and what does it mean?...sorry for my noobness...

I don't know too.
I want to know all these cool retail things

I think 3333 is a code that kant's clan/ally developed to say when they need purify.

'333' = you're anchored/petryfied
'zzz' / '111' = you're sleeped
My clan/ally are not the only ones who use this language.
It's a common language in lineage. Many others use it.

For example look here in this vid to see how effective is to say '333' rather than :"Anchor, purify pls" :

Yes, it's very common. I think that in all my clans we used this.
