Hi there, I was wondering if I followed the rules correctly, in order to create the following build..
sorc 16/ fighter 2/ warlock 2, max CHA for the eldritch blast, and taking the fighter lvls just for the action surge ability
The idea is using the eldritch blast (4 rays), then using the quickened spell metamagic from sorcerer class to cast 1 additional eldritch blast ( 4 rays), and then using the action surge for fighter cast 1 additional eldritch blast (another 4 rays), so you will be able to cast 3 eldritch blast in 1 round( 12 rays), and then 2 (8 rays)for the following 7 rounds, the lvl 2 warlock allows you to add the agonizing blast invocation, and you can choose hex spell for the warlock class... the possible damage for each ray should be 1d10+5 (cha)+1d6 = 15 average per ray
If the build does not violate any rule, I think is a pretty nasty combo, please reply with some rules that I miss or some extra modifications to improve this build
