My idea was to have 1 skill point each time you level up, skill point can by used on one of these upgrade that I wrote(to upgrade them)

(1) 5% more Hit Point(base on your newest hit point)

(2) 5% more Dmg(base on your newest Dmg)

(3) 1 Resist(Exp, Pys or Ele)

(4) 5% more Cooling or Regeneration(base on your newest cooling or regeneration)

(5) 10 more Heat or energy

(6) 5 more Heat or Energy Dmg

(7) -5% of Energy or Heat cost

(8) have 100 more Weight to use

These are thing that can be upgraded.

P.S.: If you vote for it, write a 1
