Did you not realise that that the elimination skill is a combination of puncture wound and slipstream???

Well now i see u have learnt Elimination skill. It has "merged" ur current skills which is Slipstream Strike and Puncture Wound. So you had this skill already and now you can't learn it since u've learnt Elimination one.

yeah youre right i learned elimination which one the prequisite is slipstream strike.

but look this. this is comparison of skill which i learned and skill tree. there arent skill slipstreams strike in my skill.

Point is u had this skill earlier and while u learnt Elimination it "took" your Slipstream Strike  skill. You can't learn slipstream now cause thats how new NH skills work. They merge some of your skills into one.
