You need to strike a balance between power and growth rate. Pouring too much into attack will be a waste since you will be losing on gold. Overspending on gold will make your runs much shorter.
A couple of tips:
- % to magic attack amplifies base ATK. Never neglect base ATK.
- % to gold relic is additive to any boni you have on your gear (and you should run bathed in +gold gear), so don't overspend here since ROI can be very small when adding 3% actually means a 0.002% gold income increase.
- At the beginning (and you are at the beginning) some extra hp will help you survive certain waves you can't kill on 1st round. Later on this isn't the case since you will be taking such big hits that speccing for survival costs the same (or more) than speccing for one shots -and one shots obviously have much better ROI.

+% gold fuels everything else with essence well then mystic caps so it's definately a good one to prioritize early. However, you eventually get to the point where eack monster killed gives 1.5 billion gold (1 mystic cap per monster) so at that point, adding more gold find becomes totally worthless. Then again, by that point all relics become kinda pointless since you'll be 1 shotting everything easily and sith no increase in gain for going deeper into the dungeon there is no point in pushing for a higher level beyond jsut wanting the big number.

Basically, after maxing crit chance relic, prioritize + gold find for a bit until it starts feeling expensive or you start dieing too fast, then up attack and HPs till you're able to get to the next dimension. Once you make it to a new dimension, drop a bunch of levels into your new relic then go back to gold find -->attk / HP until you unlock the next dimension. Once you make it to the final dimension, going deeper into the dungeons doesn't mean quite as much so you can prioritize gold find even more and quickly get to the runaway power portion of the game where you increase your damae waaay faster than you can progress in the dungeon and then you cap out gold per kill and get bored and quit.
