I need to know what is the minimum stats i should get to well well . LOL

To well at about 90% success rate, this is the gear my weller had when I had him:

31int weap
32int armor
126ee ice
150ee heal

I'll say this though, I went from a 100ish ee Heal up to that 150ee. It made a BIG difference (70% -> 90% success) Splurge on a nice Heal if you don't already have one.

well atm i only have low lvl caster gear but i'll save up for this man thx a lot so i guess if i can get a 40int armor and weapon with 150 ice and 175 heal i will turn this to be 100% ?

I can well at level 64 + with this setup :

41 int dagger
42 int level 40 robe
145 ee level 50 fire
113 ee level 55 wild heal.

The key is to put 5 - 10 points at the beginning into vitality, then the rest into intelligence.
It works wonders

PM me if you have any other questions.

this. monsters can crit pretty bad.

I would say aim for at least 35+ Intel on wep/armor
And minimum 130 ee 55 charm, paired with 100+ ee heal.

This, combined with vita tip given above, should give u a nice weller.
