10520 - Final Ultimate Evasion (Othel Rogue)
 

10776 - Final Ultimate Escape (Yul Archer)
For 30 seconds, increases P. Evasion + 30, M. Evasion + 90, resistance to magic + 20%, resistance to buff-canceling attacks + 95%, and Evasion rate to P. skills attacks + 95%

- pSkillEvasion is 80 85 90 95 and in l2script is
<table name="#pEvasRate">60 70 80 90</table>

- mSkillEvasion should be 0 and in l2script is
<table name="#mpEvasRate">60 70 80 90</table>

The skill is adding two times m evasion / mSkillEvasion.

First of all you're looking to the wrong data base, l2wiki is now half glory half lindvior.
Second of all after comparing our values with the client values (tauti), everything seems to be OK.

Look:
<mul order="0x30" stat="mDef" value="1.2"/>
<add order="0x40" stat="runSpd" value="#runSpd"/>
<add order="0x40" stat="pEvasRate" value="#pEvasRate"/>
<add order="0x40" stat="mEvasRate" value="#mEvasRate"/>
<add order="0x40" stat="pSkillEvasion" value="60"/>
<add order="0x40" stat="debuffResist" value="#debuffResist"/>
<add order="0x40" stat="bleedPower" value="#bleedPower"/>
I don't see here any dublicate. pEvasRate is only for hitting, mEvasRate it's magic evation, and pSkillEvation is a different attribute for physical skill evation.
Closed, not a bug.
