There is two popular Paladin Inquisitor builds in Korea.
1- Cl2, Diev1, Palla3, Monk, Inquisitor. 50 points in CON, Dex/Str 2:1. Monk in rank 7 is hit super fast the wheel and proc more damage. You can change it for Kabba1 or anything else if you want.
2- Cl2, Kriv1, Palla3, Kabba or PD, Inqui. PD if you are Cl1 Krv2. This build was supposed to be SPR but a fix bug in Zalcai in Korea dont leting reduce the crit resistance under zero kills this builds. It will work as support adding crit rate to party but not to you.
Note: If you are full SPR is easy to add 50 or 65% crit % to a party, but considering the cap on crit % is 85%, is that usefull? Normally archers have enought crit rate for themselfs, maybe now that Swordies are the new meta, it can be usefull to a party with swordies, but not sure.
Why Paladin with Inquisitor?
Wheel spread Conviction debuff. And you can spam Smite on Wheel too. And finally paladin is usefull if you wanted that class.
