Hey, I started a few days ago and opened a cleric, should I put in LUK or only in INT? This acc only for the purpose of leeches in the future. I want to gain money to open thief or warrior.
No, you don't need any LUK. The only time you would need maybe a tiny bit of LUK is if you're like me, an arch mage going for level 163 staff, but otherwise, no you're all set. There are weapons for mages that requires no LUK at all, and gear you will be able to equip by getting LUK from other gear in the future
Yes you absolutely can. It's really after 120 good end gear starts to matter anyway, and by that point you can start joining boss runs and sell leech and stuff like that to make more mesos if you want/need
