Hey there, I hope my humble guide can help some players enjoy this game :)
I know there are gray areas in the game that are little or not explained.
Please be understanding. I tried to read all the tutorials, but I found that some boxes don't appear unless you hover over them exactly (Example: the tutorial in the bastion).
I guess this must have happened to other players, so you might see information that you could already find in the tutorials. Feel free to give me feedback if you notice something missing.

Default key: Alt
Effect:
Avoid AOE damage from bosses
Grants a long frame of invulnerability
Comment: Seems obvious, but I discovered this through a misclick. I thought it was just to get off a wall.

Effect:
It is possible to reduce or even cancel fall damage if you trigger a roll during the last second before hitting the ground.
Also avoids the blocking animation when stranded on the ground.
Don't spam, you have one try.
Comment: I don't think I saw it in the tutorial.

Trigger: Jump -> Roll

Trigger: Shield during the last second before impact.
Effect:
Stuns melee mobs + provides a big counter.
Reflects any projectile with decent damage.

Trigger: Hold Main/Secondary Attack
Effect:
Can be directional.
Can be spammed after being charged.
Main Attack Loaded: 3 vertical attacks max + AOE Attack + Stun.
Secondary Attack Loaded: 2 horizontal attacks max + Push AOE on second attack.
Comment: I beg you, don't spam a 2H-sword without charged attacks! You miss all the benefits of the weapon and waste your stamina.

Yep... Yep... but good luck.

Need to break something? The best crusher is your 2H-sword.

Set Dodge on "<" (between Shift and W). You'll thank me later.

2 Rules from an NPC:
If you want better fur, avoid freezing animals.
If you want better metal, avoid burning mechas.

Two questions, same answer. I prefer increasing my elemental defense, and the best elemental defense comes from lightweight equipment.

Advantages of being lightweight:
Run/climb faster.
Regenerate stamina better.
Change direction easily.

Since stamina and environmental resistance (hot/cold) are crucial for my playstyle, I prioritize lightweight gear.
But hey! This game is about experimentation, so try Heavy, Medium, and Light armor to see what suits you best.

There is no strict boundary, but for me:
Light armor: Below 60 weight.
Medium armor: Below 90 weight.

From my experience, every 50 points, you notice a real difference.

Effect:
Lvl 1: 1 bubble, low implosion.
Lvl 2: 3 bubbles, medium implosion (really good for movement, minor damage if you hit a ceiling/tree).
Lvl 3: 5 bubbles, big implosion.

Good to Know: Whatever the radius or level, the damage remains the same.

Two Ways to Manage Multiple Blasts
Aim at one, it will explode.
Aim elsewhere, they will explode in the order they appear.

Everybody Do the Jump
Spawn one, jump in, explode blast, you can fly temporarily.
If you're skilled, you can chain them to move between two areas.
Good luck mastering this technique!

Effect:
Lvl 1: Handles one object.
Lvl 2: Handles multiple small objects or one big object.
Lvl 3: Handles massive objects + lifts big rocks + removes shields from Arkon.

Effect:
Lvl 1: Consumes a lot of mana, weak blocks.
Lvl 2: Consumes less mana, slightly stronger blocks.
Lvl 3: No mana cost, quite tanky blocks.

How to Use:
When holding the cast button, the wall follows your aim but always spawns next to the last ice cube.
You can create an ice path by aiming near yourself first, then further away while holding the cast.
If you want a mega block of ice, spam click.

Artillery Lover
Take high ground.
Create multiple ice blocks.
Throw them using Weaver's Grap.

Make a Great Wall
Spawn one block in front of you.
Then hold cast on this block and aim upwards.
I tried many ways, but it's difficult. Developers, please explain how to do this efficiently!

Drake Breath
Effect:
Lvl 1 to Lvl 3: Same mana consumption, but lasts longer.

The first blasts are significantly stronger.
