My first "Yeah Science " moment in this game

The council of reddit moderator somehow did not approve this post so here I am.

I only played 2 league 3 build so far(righteous fire, Arakaali's fang spooder, and this time lightning strike). \

I don't know most of the stuff in this game so I follow guide all the time, so there is really no room to get creative if I want my character to function properly. But this time, surprisingly, I got 3 empty white socket to work with on my lightning strike build. \

The guide says put on spectre set up to cast hast,but I really don't like it cause spectre dies all the time and I can't really keep hast on me.\

I look around on poe nija and find people use some war cry + autoexertion, but my mana reservation doesn't allow me to have more aura,then I remember arrogant support can reserve life instead, and autoexertion doesn't cost much life, then I try all the war cry to find out intimidating cry might just be the last piece of the puzzle, it has damage and movement speed.\

I finally able to make one meaningful decision on how to adjust my character ouo.

With autoexertion, you don't receive the buffs. Read the gem's description.

but I do move faster though,oh no, it might come from other things, thanks. There are way too many text I'm not reading all of them OHO. Guess I will have to try other stuff or manually click it
