Unless he wants to have companions I really don't see a point in having 3 CH.
Anyone can go to some random shop and trade some mentats for a bunch of broc flower and fruit.
Ofc.But when you are new,you don t know that.And being able to socialize-make simple task-quest is maybe more important that some hp,imho.
Also,it ruins the fun at the beginning i suppose.
i have a succesfull energy spamer but i went for 20% crit chance to increase damage
Then don t get 20 with finesse,otherwise sad damage.And yes,with spray and pray that should be working (never tested anyway)
So,in this post there is maybe everything a newbie spammer might need.
