wHAT is best for pve cleric?

its honestly about your own personal preference, there is no "Best" build ill list the common builds below and list cons and pros about it and some ways to increase your surviveability

doing 1str 9int per 2 lvls gives you high magic attack so you hit hard and theoretically you shouldnt be hit as much but when you do it hurts x{ this is due to the fact you can only wear arcane armour (high magic defence low physical defence). However if you refine physical defence necklaces and belts and shard your equips with physical defence+ you can decrease the amount of damage you receive, or alternatively refine armour's and shard them with HP+ to have a higher HP pool

an alternative to going full int(1str 9int) is to do 1str 1vit and 8int per 2 lvls this still restricts you to wearing arcane armour but you have a higher HP pool, however there are some people who argue that the HP bonus isnt very helpful as it only gives 10hp per vit point so by lvl 20 you will have an extra 100hp compared to a cleric who doesnt use vit. But this build is good for those who wish to survive a little bit longer and dont wanna suffer to much of a damage reduction. In the end its still a good idea to refine your weapon abit to make up for the loss of damage

Or you could do a Light armour Cleric 1str 1 dex 3int Per Level a light armour cleric has moderate physical defence and moderate magical defence so you take less damage on physical attacks but get hit abit harder from magical attacks compared to arcane. Furthermore, you don't hit nearly as hard as a 1str 9int cleric so therefore you might take a few extra hits from a mob before it dies, however if you refine your weapons and shard them with magic attack+ you can make up the damage lost.

Goodluck.

Why don't you look in the Cleric forum and read the guide.

8 magic 1 vit 1 strength every two levels works nicely for clerics
