Just started in on Last Epoch, an ARPG in early access. It's got some issues and there's general agreement that it needs balancing, but it's pretty good overall. Five classes each with three specialised passive trees, and every skill can also be levelled up through use to gain modifications. For example, at the moment I have a Mage whose base shooty spell has been converted to deal Cold damage instead of Lightning, his Teleport spell leaves an AOE attack at both start and finish points, and his expensive damage spell also drops a DOT on the ground. But if I wanted, I could respec all those abilities to give extra magic armour when cast and adjust his passives so he nearly always critically hits.
