In the current 280 cap. Int means fairly small portion of your overall damage. When you’re leveling with terrible gear… It’ill mean more… But as you continue to get better and better gear the amount of damage your Int contributes to your overall damage will become more and more minor.
So at 280… Right now… I’d lean towards Con heavier builds for a Chronomancer. I imagine even if I do a matk build I’m going to be using one of these: http://www.tosbase.com/database/items/273109/ which means melee. Which means need more Con to use it without getting gibbed. So again… Heavier Con build is more justified.
Here is this thing though… Years from now when we’re rocking level 400 content or something… The stacking of Int is probably going to be a thing because of the way the formula gives you bonuses for stacking Int or Str % per rank and higher bonuses as your stat gets bigger. But as of level 280 max. Int just doesn’t provide a significant bonus to end game damage compared to getting yourself some decent HP. And it makes even less sense for you to worry about Int on a build that doesn’t have much justification to stack it…
As a link/chrono you basically got your autos with that staff… And links. And flame ground is your only means of applying matk. Which is contributing but it’s not comparable to the Wiz/Ele, doppel or archer thing you’re going to be supporting.
So…
tl;dr I’d so go heavy Con enjoy being able to take a couple more hits in end game content. Healing is largely % based so HPs great. And most of your matk will be gear anyway.
P.S. Imagine Running shot buff with that staff. Cause you listened to Raspy and got the buff share.
