Strip chance depends on your dex.
taken from iRO Wiki:
"DEX difference between the caster and the target affects on the success chance. If the success rate drops below your base success chance, the base success chance will be used instead. The success rate is believed to be:
Success Rate = 5 + 2 * Skill Level + (Your DEX - Enemy DEX) / 5
Duration = 135 seconds +/- 1 second per 2 difference in DEX between caster and target"
So, let us say that your dex is 300+100, and your enemy dex is 150 total.
Success rate= 5+2* skill level which is the base strip chance(15%)+(400-150)/5
Success rate= 15%+ 50%= 65% chance of strip. Now, getting a base dex of 300 costs too much stat points that most of the other stuff is lacking. I make it a point on dex that i could strip 150 total dex characters with at least a 50% chance. no need to go overboard on the dex part, even if you are fighting high dex characters, your success rate cannot go down below 15%.
So, with that said, you will always have the 15% Base chance of lvl 5 full strip, no matter what your dex is. Which makes super high dex inferior for matyr type Stalkers.
Even with incantation samurai/thana, you will still miss on safety wall.
And the better alternative is have a 2nd bow. one bow for matyr, the other for double strafe. That way your matyr damage won't be sacrificed.
I used matyr type stalker as a main before. I was using it with the elite stalker dagger and Mix A belts. I haven't fought anyone that was able to live from matyr after I stripped them. If i am able to hit 50k+ with matyr, i hit 250k for 5 hits, and almost no class has that much hp after getting stripped. And then again, I am pretty sure I hit more than that.
