slvl question for multiplayer

So can someone explain to me what sl I should be at or around for pvp? Also, what about sl for covenants like the sun bros.? If my level is too high will I be able to be summoned to help with bosses? Thanks in advance.

150, blood brotherhood (use cracked reds or red soapstone), the "PVP HQ" of DS2 seems to be Iron Keep bridge so far. You can be summoned regardless your SL for co-op, you just have to know where to look in regards to your SL and SM.

OMG I have to go to Chancellor wellager in NG++ or kill 500 players in PVP in the blood brother covenant to get the great chaos fireball. That sucks!

@ExtremeWealth: it doesnt suck. What do u want a good spell handed to you? That way everyone would be using it.

Its good for there to be rewards like this espeacially for pvp.

EDIT: wouldnt be much of a REWARD otherwise.
