♦ All the following can be resetted from gold (in game currency).
♦ TESO is forgiving when it comes to build mistake or choices in skills. If you're not satisfied with a skill, you can reset everything & use the skill point elsewhere.
♦ Skill points aren't only use for class abilities & weapon abilities.
♦ From level 0 to 50 : Given by experience (monsters, opening locks, exploration, questing, etc.) + Skyshards
♦ From level 50+: Given from Skyshards (429 skyshards in the world) & 3 skyshards = 1 skill point.
Shyshard icon on the map thanks to a mod :
♦ Distribute between Magicka, Stamina & Health (Reminds of skyrim attribute system).
♦ Total of 64
♦ Stop at level 50
♦ Unlocked AFTER level 50+
♦ Distributed among constellations which unlock passives (reminds of Skyrim skill system).
♦ You can only invest 810 in constellations but you can gain more than 810 CP.
(Zenimax will rework the passives soon). So once you reached 810 CP, you're "max level" at this date (02/2019).
If there is anything to add, pliz post it.
