I´m having problems trying to understand this, can someone baby step me here?

My english can't understand this lines u.u

Means say your playing shi'ar imperial guard at 300 and you pop Gladiator off he will be at his 150 point mark basically your second figure you solo adventure can be anyone except warstar because he will be 177 which 150+177 will be 327 which exceeds the point cost of your team base

^-- What he said.

You can't have more points worth of "Solo" clix than the team base is worth. If you have a 300 point team base, you can't Solo more than 300 points worth of guys off of it.

nice thanks for the help they need to make this things fo baby understand

Another question is:
The TB need to have atleast 3 figures, this means i cant pull out in solo adventure and let 1 or 0 in the team base?

Correct you have to leave at least three figures on the base unless they have a trait that says otherwise like Trinity of Sin has 3 figures but it's trait allows for one to come off leaving 2

You must have a minimum of 3 characters attached to the Team Base at all times (unless stated otherwise)

Sorry for bump this up too, BUT what happend ifthe format im playing is 300pts and i have a team base on 300pts can i still solo adventuring figures?

Yes, absolutely, so long as you follow the above (and now below) given rules:

1) No fewer than 3 guys left on the base

2) No more than 300 points of guys Solo Adventuring at the same time.
