Loop Hero

For this achievement is necessary to kill Omega the last boss on chapter IV 6 times, to track your progress go to encyclopedia and see the dialogues with omega

Since there isn't really a true guide here I'll add one to help make this less of a grind. You have 2 main paths, a Thicket/River Necromancer or a Damage/Potion Warrior. The warrior depends a lot on trait luck but you can afk it for the most part. I always went with Necro as it is the most consistant and can go infinite AFK if you want to farm mats so that is what this guide will cover.

Necromancer Build

Cards
- Cemetery (for early good items, omincron it later on) + Grove
- Spiders + Battlefield
- Forest + River (Desert and Suburbs optional)
- Oblivion
- Ancestral Crypt

- That is all you need, do not take any other cards as all other enemy spawns counter this build.
- Your goal is to snake the river around the map in a zigzag pattern and place only thickets. Rivers DO stack AND multiply on the same thicket. So with 4 rivers touching 1 thicket you get a +16 instead of +2.
- Omincron is used to delete Villages (from thickets) asap and Cemetery in late game.

Camp Items
- While camp items are not very important for this build there are a few that do help.
- Furniture: Alchemist's shelf
- Tools: Skinners Knife, Jewelers Lens, Herbalists Sickle, Kitchen Knife
- Food: Cheese (stacks with Ancestral Crypt), Loaf of Bread
- Jewelry: Old Painting

Out of all these I just filled the rest with food as it stacks nicely with Kitchen Knife. Even though you don't need much HP it is always nice to have.

Equipment
In priority you want:
- Max Skeletons, Skeleton Level, Skeleton Quality, Magic Shield

I sometimes had a grey level 11+ ring that had +1 to max skeletons as that is how important it is. You want 5+ asap. Once you get 5 you have some leeway. If you find an equipment that drastically increases something for example a Grimore that increases skeleton level from 2.45 to 6.56. Take it, but do not go below 4 max skeletons. For quantity I found around 25-30% to be good enough.

Traits
In priority you want
- Unseen Care (the key to this build), Laying One's Life, Art of Control, Field Practice, Residual Heat, Edge of Impossible.

For Boss traits Omnicrons Technique is best, then Treasure Hunter, Skilled Architect (best taken early), Their own Peril, Lightning Fast, Bottomless Bottle.

Strategy
Here is how this all works together.
- Every kill you get of a soul enemy you gain +3hp from the Crypt and +1hp for every cheese item. I was getting around +14 max hp per kill.
- Prioitize Ratwolfs as they have a soul, spiders do not.
- Summoning Skeletons is based on attack speed. The higher attack speed the faster you can summon skeletons. You yourself won't be doing any damage.
- By staggering Rivers/Thickets you should have around 400% mininum attack speed by the end boss.
- Every time you summon a skeleton with the Trait Unseen Care it increases your Magic Shield by 0.5 per skeleton you summon. And as you summon skeletons so fast your shield should go up a couple points every fight.
- The weaker your skeletons the faster they die allowing you to summon more, increasing magic shield, however the more damage you can take. Its a balance between skeleton level and magic shield if you have the trait.
- I always kept skeleton level above enemy level

You may not get Unseen Care but this build can still work, you'll just have to prioritize Magic Shield on your Amulet.
