Returning player, need help with mage build!

[Misa]

Hi, I'm looking to return to the game after quite a long period of time. However, i'm not sure what build to go on my enchantress. She's level 53 currently, pure INT. She's equipped with keeper gear, but i'm not really funded (only have 90k gold). I've seen other enchantresses using axes and shields, so I assume they're STR/INT? I'm looking for the best build for PVE currently, but can't really find any. Which build is best for PVE, pure INT or STR/DEX or STR/INT or whatever else build?

I'd also like an optimal skill build and recommended gear, thanks!
