I don't think cleric need much STR, as they get 2 STR per level gain <.< That pretty a lot for a healer.
I'm going for full END or 2 END : 1 SPR build. At high level you will surely need more mana, HP, and you will definitely need both physical and magical defense (some one said, invincible ?)
With high SPR we will also have high crit rate, that will make up for dmg loss from adding no STR.
And why do we need to add STR, when cleric weapon has the highest base dmg, greatest bonus from upgrade
DEX is worthless on cleric, so is INT.
Summary, my cleric wanna-be:
- 2 : 1 END/SPR build
- STR/END/SPR equipment
- Stun/Bleed skill abuse
