If you guys want a braindead build, I would highly recommend building around the water spell book, which is purchased from the Central Noer Market. I went from struggling each fight to crushing every single encounter after I learned about the item.
Specifically, the water nova skill is very broken. It's a 360 degree attack that comes out fast, knocks enemies back twice, has great range, and does good damage. Just spamming this allows me to clear a group of enemies in seconds. Not to mention, I will accidently clear traps and hiding enemies because I was spamming this. It's great for abominations for that reason.
This skill very much reminds me of wraith of the gods from Dark Souls 1 (also a very broken spell in that game).
The other benefit of this build is that you increase wisdom, which lets you talk your way out of encounters, and is very useful when you're escorting a quest companion that dies easily. You also get to see unique wisdom-based dialogue, and wisdom equipment is better than attack equipment (with gear mostly from Elise, I was able to hit 61 wisdom with a level 40 Lona. This is compared to 54 ATK using an offensive combat-skill focused Lona).
To make the build work, you need a Lona with the timid and mana knowledge perks. I would also recommend masochist as well. All other trait points go into wisdom. In your backpack, have an aqua staff (for single target DPS to prevent accidently killing a quest escort) and vile scepter (for distraction minions when you're low on stamina). Frag mines are also good for the stronger bosses.
To earn enough money to purchase the book early game, I would recommend buying as many frag mines as possible, and going to the arena. Reminder to loot the dead animals to get food to save funds.
