According to this - Is it possible to Twin Spell Dragon Breath or Booming Blade? We can Twin the booming blade spell
Now if I pick
- 2 lvls in Fighter to get action surge
- 3 lvls in Sorcerer to get Metamagic and then 1 more to have enough for my plan
- Get the twinned spell and quickened spell metamagic options
We have 1 action surge, 4 sorcery points and a Booming blade cantrip I should be able to now use my standard action to cast booming blade then Twin it for 1 sorcery point, quicken another one for 2 points, then use action surge and twin the cantrip again.
This results in 5 weapon attacks in a row (Yes we did just deplete our resources from both classes, but it's possible)
The final result is 5 standard weapon attacks which will each have another 1d8 Thunder damage added onto them from the cantrip and possibly per each adding 1d8 if they move willingly (Although this effect might not stack, if anyone finds out if it does, please put the source in your answer)
Now, yes you can't exactly target a single creature with all those attacks, but it still seems a little broken.
That's why I want to ask if there isn't something I've missed or is this really possible?
The potential damage provided all attacks hit and the caster is using a great weapon (like a Maul or a great axe) would be 3d12+3d8 (+3d8 if the target moves afterwards) and 2d12+2d8 on an adjacent target, if I understand this right.
