A-bombs work too.
But, all humor aside, neither Hand grenades nor a-bombs are necessary.
Multiclassing
is optional.
The perspective that seems to be pervading the thread that NOT allowing MC is somehow doing something "wrong"...cuz the players want it...is ...well, really irritating to me.
And another thing... [this has nothing to do with you, DannyAlcatraz, just happen to have quoted you]
...I don't know about anyone else [probably not since it seems so rare an occurrence], but I am really getting tired of being made out to advocate "badwrongfun", being "adversarial", or "arrogant" and/or insinuating (if not stating outright) I am a "bad DM" any time anything is brought up
advocating DM empowerment.
The DM is allowed to make choices for their game. Regards of what players say, what players want, what players think they are entitled to. The DM CAN SAY NO! They SHOULD say no. They should be fair. Yes. Note, not "balanced", fair. They should be as consistent as possible...Yes. But it's not always possible and players need to accept that. And they should damn well HAVE A GOOD TIME DMing! And if that means NOT adding in options that the players say they want...so fraggin' be it!
Is it going to "ruin" your concept that you can't be a Paladin/Warlock/Sorcerer? Is it going to "ruin" your game/night if the DM says no MCing in their campaign...or even in this single campaign or one shot? Or does it just mean you work with what you got? The DM will still be shelling out enough fun adventure and excitement in a fantastic world of their design [as shaped and effected by the PCs and their choices and actions] to shake a handful of dice at. You still have loads of "meaningful" decisions, both in character creation and roleplaying, to make.
But you can't have fun with just a Paladin? She's a "bad DM" cuz they won't let you use spell points to max out smites? You character is no good now, because you have to limit your spell selection to Eldritch Knight [or, ya know, play an EK and get DM ok to use different spell schools! Still don't need MC for that.] He's telling me "badwrongfun" cuz he won't let me be a Fighter/Mage...and get Second Wind and Arcane Recovery and Extra Attacks and Ritual Casting and and and...?
I just don't get it. Just a big meany DM, I guess.
