I’ve recently jumped into a game of Dragonlance despite the fact that all I know of D&D stems from Solasta & the old Neverwinter Nights games. I came to play an Elf Fighter that I want to subclass to Echo Knight. The GM was so friendly to let me rethink my choice of cantrip, which I humbly seek to be advised on. My current favourite is Booming Blade, which I find mixes well with the ability to move out of the current melee by switching with the echo. It also scales in damage the same way I’d receive extra attacks, so I won’t be missing out on much damage in my view. What would you choose, and why?
I’m a total noob without any knowledge other than the computer games mentioned. I also used some kind of character builder, not sure if from R20 or D&D beyond - which also had a limited list. I chose shield, which isn’t a good choice if you want your Bonus action for other stuff like being someplace else^^
