To improve your character at the moment you need to focus more on 1-2 skills you like, target farm / buy items boosting them
You also need to focus on a damage type and have almost all of them with appropriate %damage bonus (for fire %Fire %Elemental %All damage are appropriate)
Here’s a list of items with modifers to every skill https://www.grimtools.com/db/items/skill-modifiers
Look at @Nery Beginner Physical Forcewave Warlord as an example how it’s done: https://www.grimtools.com/calc/q2MoAk1Z
from this topic ⚔ Nery's beginner build collection
To solve energy issues you could use specific components or devotions.
For example you could decide to focus more on Fire Aegis of Menhir and target farm Shield with - skill recharge to the skill. Or maybe some items to Vire’s Might or Judgement Fire / Physical Forcewave Cadence /Righteous Fervor with Default attack procs Eye of Reckoning etc.
