The game has multiple characters - each has their own specific abilities
Talents are passive abilities for making your characters stronger permanently

Skills can be upgraded with 3 of the similar levels

Max level is 3
From Lvl 1 to Lvl 2 = 3 Lvl 1
From Lvl 2 to Lvl 3 = 3 Lvl 2

Start the game with 3 skills

Each realm require a set amount of spirit stone to unlock
Or level up a certain amount of time to unlock more slots for skills

For each real unlock will gain passive abilities in game, 1 of 3 choices

what is happening
>The rules are basic, w a s d - to move around and shooting are automatic
>Spirit stones (main currency to upgrade and buy abilities in game)
This are given through killing enemies with chance or with each level up
>There are synergies on the left to show what can be linked with each other to be stronger
(I am not hardcore enough to understand the synergistic nature but it's all intuition)

how to win
>Spawned in start kiting (attacking run circles around the enemy at a safe distance)
>First level up buy a skill
>Second level up refresh the given skill option to gain 3 of the same skill (upgrades said skill to be stronger)
>At least 1 AOE (area of effect) abilitiy to allow safe aggro
>Consistently upgrade and buy new skills
>Bosses are easily defeated with the first given skill if its at lvl 3

Done you have won the first game and know the basic on what can be done in game.
Hope you will have fun <3
