Need help with BG combo

Hi all, GT0TKACA here. I have try the combo discussed on this thread . It seems good. But i really need to know how to calculate it. i mean, people says "150% Snipe"... or similar. How exactly i know that my ulti skill have 150, 130, or just 90% damage? would you all explain it?

How to calculate that my Snipe has 150% damage? and can apply the calculation on another ulti skill, like Tempest or any ulti?
Tyvm. And i do apologize for my bad english.

 

Firstly, this combo costs 5mp total. Change your swift tags to Consecutive (i.e. Save, con, con, con, smite, con).
Also your snipe will be 150% dmg on smite because you have 3 skills inbetween the initial save tag.

 

Thank you for fast reply
So, any skill will be 150% if the condition are: Skill 1 (save)> skill 2> skill 3 > skill 4 > skill 5(150%). Right?

 

And one thing, this skill are awesome with bowgun, but very bad with bow. and i did proration. do i miss something?

 

Yes:
Skill 0 (opener) > Skill 1 (save) [-80%] > skill 2 [-60%] > skill 3 [-40%] > skill 4 [-20%] > skill 5 [-0%] (smite) [+50%] > skill 6 (ender)

Bowgun does more damage than bow, but has lower stability (i.e. varies more). But bow has higher proc rate (tumble, paralyse, slow, armour break etc)

 

ah, i see. i follow ur advise about putting cons on my skill. AWESOME! Thank you very much, Lenwok
