Thx. I Think i understand it now better. I readed some build guides about sorlock based on EB and sorcery points. But now i realize you cant spam this combination because sorcery points only recharge after long rest. So i try 2 points in Warlock (fiend) and 10 in Sorcerer (dragon), so i can cast more then 1 time in a round Big spells like Haste oder Fireballs. I thin this a alot better then just focus on EB.
